Comment 1 David Edmundson 2012-07-09 20:17:33 UTC 
I can't do anything with that backtrace. 

It's crashing inside Qt, called from an X11 event.
I would need gdb attached...or something more.

I'll run everything through valgrind see if that spots anything.

New crash information added by DrKonqi

ktp-text-ui (0.5.1) on KDE Platform 4.8.4 (4.8.4) using Qt 4.8.2

Got the same crash using latest filter branch. The backtrace is exactly the same (and useless, sorry)
Anyway perhaps it can be reproduced somehow...

[14:25] <d_ed> drdanz: have you seen https://bugs.kde.org/show_bug.cgi?id=303245 in the last 6 months?
[14:26] <drdanz> d_ed: Not recently, I don't know if in the last 6 months though...
[14:29] <d_ed> can I close it?
[14:29] <d_ed> or not? I can't do anything to fix it atm
[14:30] <d_ed> with the information there
[14:43] <drdanz> d_ed: yes close it...

Seems like this is a bug in Qt, which has possibly fixed itself.
Either way it's not something I can fix.
