i don't see any crash backtrace here.

Please give some more info

I have a similar problem on Arch x86_64.
Application always crash after firts typed letter, with ONLY one error in console: "Segmentation fault".
It applies not only chromium (when typing in address bar) but in other apps too and so far i can confirm:
*gksu - when typing password and 'run' commend when started without argument.
*banshee - when typing in quick search box.
*chromium - typing in address bar.
Applications don't crash when pasting text into these text fields.
I didn't find any related erros in /var/log/errors.log.

It works here:
a) are you up 2 date? (Check your mirrorstatus)
b) do you have some foreign glibc installed -> pacman -Qm
c) strace / gdb chromium

I can't reproduce the crashes on either i686 or x86_64.

More information is certainly needed. (See jelly's questions.)

a) Yes, I'm fully updated :D
b) I have glibc from official repo
# pacman -Qm
gnome-shell-extension-autohide-topbar 1.0-1
laptop-init-script 1.1-1
libflashsupport-pulse 20110625-1
plymouth-git 20110625-1
telepathy-sunshine-git 20110625-1
c) Output in: attached file "strace.txt"

strace and gdb are two different debugging tools. You should run them individually:

1) In the case of strace, run 'strace -o strace-output chromium' and upload the strace-output file.

2) In the case of gdb, run 'gdb /usr/lib/chromium/chromium' and then in the gdb prompt:

a) Issue the command 'run' to begin the execution of Chromium.
b) Wait until it freezes and go back to the terminal running gdb.
c) Enter the commands 'set logging file gdb-output' and 'set logging on'.
d) Get a backtrace with the command 'bt full' (hit the return key until there are no more lines).
e) Exit gdb by issuing 'quit' and upload the gdb-output file.

Debugging symbols are stripped from the chromium binary (and the libraries it uses), so we won't get very useful output from gdb, but we'll have a better idea of what/where it fails.

'strace' generated huge file so I uploaded it to speedyshare :)

I'd say you configure gtk2 config isn't right because there are numerours of lines with file not found.

Can you upload the output from gdb as well?

strace and gdb output

I'm having this exact same issue, hoping my strace & gdb outputs can be of some use. I'm on an x86_64 system. Thanks.

I had this exact problem, then I ran pacman -R an old google-talkplugin that I had previously installed from AUR (and forgotten all about).
Note that just disabling it from within chromium did not work. (Yes, I had to be quick)

Hope this helps you guys as well.

That resolved it for me, completely forgot about that plugin (b/c it doesn't work). Thanks Hans-Peter!

Thanks for pinpointing the issue Hans-Peter; I was pretty much lost. :)

tirrex and Krzychek, can you confirm that removing google-talkplugin solves the issue for you as well?

I haven't installed google-talkplugin even :D
My system looks like one big error(because I'm still studying and playing with Arch), so I'm going to reinstall everything.
EDIT:// After re-installing the system started to be super stable and this "bug" goes away too... So sorry for taking time, it was my fault :/

@Krzysiek: hadn't seen your edit there. :)

I'm closing this bug since it seems to be caused by the way unsupported packages interact with Chromium.
