Description Joris Guisson 2013-05-12 15:03:58 UTC 
Found some similar bugs, but that seemed to suggest that using the qt packages from ubuntu 13.04 would fix it. So upgraded to latest ubuntu version. Still crashing all the time while typing. Makes kdevelop extremely unusable.

Don't know how to get a better backtrace, I have qt4 debug packages installed:

Reproducible: Always
Comment 1 Aleix Pol 2013-05-12 17:54:31 UTC 
It does look like a nasty crash, but the backtrace is quite broken. Can you please provide further information so that we can investigate?

Maybe the project you're triggering the problem with? Or a better backtrace?
Maybe you can run it with valgrind?
