I sure didn't expect it, but I _can_ reproduce this one!
1. Use QEditor, start a search
2. Start another find (menu is reachable even if shortcut isn't)
3. run a few find next with the second dialog
4. Close it and attempt find next with the first dialog
-> Crash!
An interesting thing in my backtrace is that libGL (from nvidia) seems to be involved!?

OK, at least it has nothing to do with the FileSelector. Running without it, or even without any project loaded results in the same problem - KDevelop closes. The reported crash comes, as seen in the backtrace, while KDevelop is closing down (and without a project, I didn't get a crash from this) but _why_ are we closing down? I'm beginning to suspect the problem lies with QEditor. Changing component. Yes, it is QEditor, the same thing happens with the replace dialog. The reason KDevelop closes is one consequtive call too many to kapp->exit_loop(). Will try to fix it later tonight. Subject: kdevelop/editors/qeditor CVS commit by dagerbo: If there is already a find or replace in progress when a new is started, close the first.

Version: CVS (using KDE KDE 3.1) Installed from: RedHat RPMs I was doing a find next when this happen but looking at the stack it is not obvious that it has anything to do with find. I also think I had one find already started that I had forgotten about and then started another. [New Thread 1096328320 (LWP 10255)] [New Thread 1116949808 (LWP 10256)] 0xffffe410 in ??
