Segfault when pressing Ctrl+Space in Gimp

[Jens B.]

Hi there,

as the title says X crashes when pressing ctrl+space in Gimp, thus I first filed a bug against Gimp, but the guys there told me that this would most propably be an X bug, thus here I am.
After the crash lightdm starts asap and I am presented with the login prompt.
I hope that ubuntu-bug attached all the necessary files. If not, I can provide more, as I can reproduce the crash quite well.

Please tell my if and what data you need to investigate this bug, I'd be very happy to provide it if possible.

Kind Regards

Jens

Also here is the log after a crash. I believe the log from ubuntu-bug is useless

[Jens B. (jens-bavendiek)]

Here is the crash file from /var/crash

[Timo Aaltonen (tjaalton)]

Can you reproduce the crash? I haven't been able to.

[Jens B. (jens-bavendiek)]

Yes, I am.
I can do so by pressing Ctrl+Space when editing an image in Gimp.
I'd be happy if I can provide any needed info, please tell me what you need.

[Timo Aaltonen (tjaalton)]

ok, could you get a backtrace from it:

[Jens B. (jens-bavendiek)]

Sorry for the late reply, I was having some troubles with the backtracing.
Hopefully everything is as you need it.

I apologize again, for beeing so slow.
Kind Regards,
  Jens

[Timo Aaltonen (tjaalton)]

Thanks for the backtrace
