Description Tom Vollerthun 2008-02-06 21:44:33 UTC

Version:            (using Devel)
Installed from:    Compiled sources
Compiler:          gcc (GCC) 4.1.3 20070929 (prerelease) (Ubuntu 4.1.2-16ubuntu2) 
OS:                Linux

Steps to reproduce:
- Have desktop effects enabled
- Have the "Flip Switch" and the "Box Switch" enabled
- Make sure there's only one window open
- Press Alt-Tab more than once

Seems as if the crash does not necessarily occur - right now I can restore normal behavior with opening another window (p.e. alt-f2, type "konsole" blind) and pressing alt-tab again. After releasing the keys, the desktop goes back to normal with the correct window active.

I'll add a traceback once I can provoke a crash again.

reason is animation is also started if there is only one window. It also occurs if only flipswitch is selected.

I just read the commit digest and found you've fixed this already weeks ago - that's just great! Thank you - you rock!
