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.

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.

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
