Sentry Crash Report:

Description King_DuckZ 2010-05-22 18:27:11 UTC

Application that crashed: dolphin
Version of the application: 1.3
KDE Version: 4.3.5 (KDE 4.3.5)
Qt Version: 4.5.3
Operating System: Linux 2.6.31.13-desktop-1mnb x86_64
Distribution: "Mandriva Linux 2010.0"

What I was doing when the application crashed:
Open two windows of firefox (or possibly any other application)
Open one window of dolphin and select multiple files
Make sure that in taskbar firefox didn't get grouped yet eg you have 3 icons now (option only group when task bar is full activated)
Drag your multiple selection onto the second (any?) firefox's window
Observe how taskmanager tries to group firefox's windows and proposes a list of the windows you want to drop onto, then crashes

Non-grouped windows should not get grouped unless a new application is launched and the taskbar runs out of available space

I just re-tried, I'd like to add that once firefox gets grouped and taskmanager shows the list of the two firefoxes above the grouped icon, you need to move your mouse pointer onto said list in order to reproduce the crash. Not that the selection is never really dropped in my test.

Thanks for the bug report! This is most likely related to bug 203887 (or bug
200583).
