Arch Linux

Works Perfect here.....

Same problem here with same errors in dmesg. Please let me know if any information is required.

strace with qtcurve-gtk2 1.4.0-1:
...
access("/home/markus/.kde4//share/icons/oxygen/16x16/actions/zoom-out.png", F_OK) = -1 ENOENT (No such file or directory)
access("/usr/share/icons//oxygen/16x16/actions/zoom-out.png", F_OK) = 0
read(7, "icon>\n#\tstock[\"gimp-tool-pencil\""..., 4000) = 608
read(7, "", 4000) = 0
close(7) = 0
access("/home/markus/.config/qtcurve/gtk-icons.en_US", F_OK) = -1 ENOENT (No such file or directory)
access("/home/markus/.config/qtcurve/gtk-icons.en", F_OK) = -1 ENOENT (No such file or directory)
--- SIGSEGV (Segmentation fault) @ 0 (0) ---
+++ killed by SIGSEGV +++

strace with 1.3.0-1:
...
read(7, "", 4000) = 0
close(7) = 0
access("/home/markus/.config/qtcurve/gtk-icons.en_US", F_OK) = -1 ENOENT (No such file or directory)
access("/home/markus/.config/qtcurve/gtk-icons.en", F_OK) = -1 ENOENT (No such file or directory)
getuid() = 1000
read(6, "ess = 4\n}\n\nstyle \"qtcurve-combo-"..., 4000) = 3683
read(6, "", 4000) = 0
close(6) = 0
...

so it looks as if 1.4.0-1 segfaults in the getuid() syscall.

i suggest that we should downgrade the version from extra. for one guy in the forums, kde was crashing entirely

please Octoploid, try with a new user.
I am using qtcurve-gtk2 with firefox and sonata here, and I haven't issues.

Andrea,
you are right, there are no problems if I use another user (root in my case).
But that does not help me much. Where should I look next?
Could it be a config file somewhere?

(And BTW I'm not the only one, who had hit this bug see:
http://bbs.archlinux.org/viewtopic.php?id=97257 )

Same issue for me: gimp, gnome-control-center, gvim, etc. would consistently segfault while opening. A gdb trace showed qtcurve as the culprit.

The same thing happens as my normal user, as root, or as a fresh user I created from scratch to test this.

The problem is solved for me by doing any of the following:

downgrading qtcurve-gtk2 to 1.3.0-1
switching to a non-qtcurve GTK theme
killing gnome-settings-daemon (I use KDE and run gnome-settings-daemon manually)

When I delete ~/.gconf/desktop/gnome/interface/%gconf.xml and then startx,
I can change the theme back to qtcurve. Everything is fine until I start another
gtk application, which will then segfault while opening. After that _any_ gtk app
will crash while starting.
1.3.0-1 is perfectly OK.

So please delete 1.4.0-1 from extra immediately, before more users are hit by
this nasty bug.

I'm the author of QtCurve. Can someone who is having this problem email me (address is in AUTHORS file). I've made some changes that *might* fix the issue - but seeing as I cant reproduce the fault myself, I have no way of knowing! So, I'd like to send a modified QtCurve to someone for checking.

This bug affects me, too. Adding myself to the CC list.

Please try v1.4.1 of the Gtk2 QtCurve - just uploaded to kde-look. This has been reported to resolve the issue.

1.4.1 fixes the bug for me. Thanks.
