Comment 1 Milian Wolff 2010-10-28 14:11:57 UTC 
looks like a Qt bug to me. Maybe you could run kdevelop through valgrind if you can reproduce the crash. Or give us a way to reproduce it.

Otherwise nothing we can do about it.
Comment 2 Steven Sroka 2010-10-28 16:51:09 UTC 
It might be a KDevelop bug. I'm hoping that if it is, that it was fixed in KDevelop 4.1. There was a bug fixed regarding an innocent crash in KDevelop:

"Fixed a common crash on shutdown (which never resulted in data losses but was very annoying)" - http://dot.kde.org/2010/10/26/kdevelop-41-brings-git-integration

If it's a Qt bug, then I have to wait until Qt 4.7 becomes stable on my OS.
Comment 3 Milian Wolff 2010-10-28 17:12:04 UTC 
it's definitely not the bug I mentioned in the release announcement. so if you ever come around to get a valgrind report then send it to us.

thanks

Upstream bug, likely.
