The crash happens deep within Qt. Is it possible that you're using Qt 4.5?
@David: Thats what I thought first too, but the segfault is apparently happening in thread 7 in parsingEnvironmentFile(). At least thats what visible in the output right before the "thread apply all bt".
(In reply to comment #1) > The crash happens deep within Qt. Is it possible that you're using Qt 4.5? Yes, I'm running Qt4.5 from OpenSUSE's buildserver.
I got this crash, too. Using Qt4.5 from openSUSE Build Service. But IIRC this happened to me before I did the upgrade to Qt4.5, too. What I did is adding <code>#include ""</code> to one of my files. It doesn't crash when it contains an existing file.

Can either of you two please re-test with latest trunk/, David fixed an issue with C++ support last night which tried to access a directory like a header file.
As of r924867, this should be impossible to happen.
