Description Cypress Twist 2005-11-30 17:36:15 UTC 
Version:            (using KDE KDE 3.5.0)
Installed from:    Ubuntu Packages
Compiler:          gcc version 4.0.2 20050808 (prerelease) (Ubuntu 4.0.1-4ubuntu9) 
OS:                Linux

I'm using kubuntu 5.10 and updated KDE to version 3.5 there's a very irritating bug that causes kwin to crash from time to time. I haven't been able to reproduce it, but I think it has something to do with using the Show Desktop button in the Panel. Anyway, when i maximize a window, KWin crashes sometimes. Here's the backtrace:

Applications that are loaded during the crash: NetGo, KGet, KNotes, Kopete, Kxkb, KLaptop, KMix and SuperKaramba (these being the ones in the tray) + Firefox 1.0.7 and Evolution, maybe others.
Comment 1 Cypress Twist 2005-12-01 09:39:34 UTC 
It happened again: I pushed "show desktop" in panel, opened up aMule from a link on the Desktop and KWin crashed again.

Comment 4 Alexander Frey 2005-12-07 01:14:44 UTC 
Strange, but you have quite the same apps running as I do. Has it something to do with superkaramba ?
I also use the showDesktop button very frequently.

regards
Comment 5 Cypress Twist 2005-12-07 06:59:08 UTC 
I disabled superkaramba and it still happens.
Comment 6 madman 2006-04-05 13:48:57 UTC 
Actually, it still happens with 3.5.2
I encountered it while trying to start pingus (w/OpenGL) on full screen. Just tried again and it didn't crash.
It happens with other applications as well and has a quite random character.

I couldn't find a reason for that - happens with different applications. Can't send a backtrace - don't have any debugging binaries
Comment 7 Alexander Frey 2006-04-05 14:03:04 UTC 
The last time I encountered the problem was with kde 3.5.1. Now I'm using Gnome to get some fresh air.
