Firefox 1.5.0.6 (mozilla-firefox-1.5.0.6-1 package) crashes when visiting certain sites. This does not happen with Firefox 1.5.0.6 obtained from mozilla.com, so I assume it's an Arch Linux bug.

Reproducable: Always
Steps to reproduce:
1. Open Firefox
2. Visit http://www.mobilize.in (it's one of the sites that cause a crash)

Expected results: you see a webpage (it's in Russian so don't worry about messy content)
Actual result: firefox silently and quickly closes the window soon after header of the page appears in the title bar. No errors or tracbacks are reported.

I guess this problem may depend on some local settings (like fonts installed etc.) so I'm ready to provide any extra information concerning my system you'll need.
This task depends upon

4 questions:
- extensions?
- plugins?
- do you use composite with X.Org?
- what do you get when you start firefox from a terminal and visit the offended site?

> 4 questions:

Only DOM Inspector, installed by default - nothing more
> - plugins?
Flash and Java (both standard Arch 0.7.1 packages), but they're irrelevant - Firefox crashes even when no plugins are loaded
> - do you use composite with X.Org?
Nope, I'm on Unichrome Pro video card ;)

As one could expect, segfualt. I've tried to run firefox in debug mode (-g). According to the output, it receives SIGSEGV in NSGetModule() in /opt/mozilla/lib/firefox-1.5.0.6/components/libgklayout.so

Thank you for a quick answer!

What GTK theme engine do you use? Could you provide a full backtrace generated from the -g option?
Comment by Valentine Sinitsyn (Val) - Thursday, 31 August 2006, 17:55 GMT
> What GTK theme engine do you use?
QtCurve 0.42.1. I've tried to use different one (Raleigh) with no luck.

Ok, it's attached to this comment (whole gdb session)

could you run a "bt full" after it crashes?

Does is also happen when you run firefox as "MOZ_DISABLE_PANGO=1 firefox"?

Yes it works. It's interesting that it works with Pango enabled from one account on my machine and does not work from the other. They are using different fonts and probably that's is an issue.

The second thing worth mentioining is that I'm using pango-2.10.2. I know that mozilla-firefox-1.5.0.6 does require pango>=2.12 (and gtk-2.10) but, again, it works on my second account.

[OFFTOPIC]
The reason I'm running Firefox with semi-satisfied dependencies is that Arch Linux, unfortunately, does not provide means of upgrading the system. You can have 0.7.2 or you can have -current - nothing more, there is no "stable" and "development" branches as in other distros. And it's ver-very unconvenient, especially if you don't have broadband internet connection. You are going to upgrade only a browser (10Mb worth), but instead you'll need to download a whole bunch of libraries you don't need (I'm very happy with gtk-2.10). This would be very nice to have separate Arch Branches, say, 0.7.2 (with major system libraries and tools frozen) and current.

The point is that I can't reproduce it. Please update to pango 1.14.2, glib2 2.12.2, cairo 1.2.4 and gtk2 2.10.2 to make sure this is not the issue. It could be a bug in pango, it could be a bug in firefox, but running firefox with a version of pango, cairo, gtk and glib older than the one it's compiled with is asking for problems.

Ok, I'll try to download these packages in the coming days and say if this helps.

I've updated evrything (except libcups required by gtk-2.10 - I'm alreadyhave it on my system) and it still crashes. It's not to mention I've broken the whole my sytem upgrading it manually (without using pacman -Sy). It's reaaly-really pitty there is not stable branch for Arch.

I think it's one of the local-installed font in your profile that makes firefox crash. Could you try to use gnome-font-viewer on those fonts? If gnome-font-viewer crashes, the bug is in pango. If it doesn't then the bug is in firefox' pango renderer and we have to look into firefox for the problem. If you can find out which font triggers the crash, I would like to have that font, or at least a link to where to get it.

I don't have locally-installed font and the only fonts on my systema re mscorefonts from Arch package.
I don;t have gnome-font-viewer either, sorry :(

What version of freetype2 and fontconfig do you have?
Comment by Valentine Sinitsyn (Val) - Friday, 01 September 2006, 10:32 GMT
> What version of freetype2 and fontconfig do you have?
freetype2 2.1.10
fontconfig 2.3.2

Firefox has been updated with a slightly better pango patch, could you try the new version?
Comment by Valentine Sinitsyn (Val) - Sunday, 03 September 2006, 16:12 GMT
Sorry, it still crashes... :(

Maybe it's better to close this bug? The problem is certainly not so easy to find and Firefox works just fine with Pango disabled.
Of course, if you'll go to find out what's going on, I'm ready to help you with the debugging.

Several memory corruption fixes have been applied to firefox 1.5.0.7, is this fixed now?
Comment by Valentine Sinitsyn (Val) - Wednesday, 27 September 2006, 13:25 GMT
I think yes - I visited the site I wasn't able to see before
Thanks a lot - and feel free to close the bug
