Description Dan Christensen 2004-01-12 19:46:06 UTC
Version:           3.0.0.b2 (using KDE Devel)
Installed from:    Compiled sources
Compiler:          gcc 3.3.1 
OS:          Linux

Steps to duplicate:
1. Open up multiple files in KDevelop (10 - 20)
2. Attempt to close all files by clicking Ctrl+W repeatedly
3. KDevelop crashes (not necessarily on any particular file)
I can duplicate this every time that I try. However, you can workaround the problem by pausing for a couple of seconds between each keystroke.

Can you reproduce it in KATE?
If you can it is a KATE bug.
Comment 2 Dan Christensen 2004-01-12 20:11:22 UTC
I cannot duplicate it in Kate.

Please, what KDE version are you running?
Comment 5 Jens Dagerbo 2004-01-12 20:52:26 UTC
I think I know what's going on, but I can't make it crash here.

Comment 7 Dan Christensen 2004-01-12 21:56:09 UTC
I am running 3.1.94 KDE installed from Suse RPM's. My kdevelop is compiled from CVS source... I believe that I last updated on January 9th. I will apply your patch, recompile and let you know if it worked.
Comment 8 Dan Christensen 2004-01-12 23:04:05 UTC
The patch seems to have fixed the problem for me. Thanks!
