Description Carth Onasi 2010-01-12 13:18:37 UTC 
Application: plasma-desktop (0.3)
KDE Platform Version: 4.3.90 (KDE 4.3.90 (KDE 4.4 RC1))
Qt Version: 4.6.0
Operating System: Linux 2.6.32.3-desktop-2mnb x86_64
Distribution: "Mandriva Linux 2010.0"

-- Information about the crash:
I started Firefox, then downloaded some files (Download manager was open). Switched to other desktop and done usual work.
When I came back. There was duplicates of Download manager (2 items of Download Manager in taskbar and one group of Firefox with 3 items (One Internet browser, two Download Manager), but there was only one Internet browser and one Download manager running).
When I clicked right button of mouse on one item in taskbar of Download Manager and choose "Close" -> Plasma crash.

I have settings on taskbar to display only windows from actual desktop.

The crash can be reproduced some of the time.

- Have you tried to repeat the situation to check if Plasma crash again ?

New crash information added by DrKonqi

Yes, I tried do it again, but now I started Firefox on Desktop 1, activated Download Manager, start 5 windows of Dolphin, started gnome-terminal,... So Dolphin became group and there was other 3 items in taskbar (Items must be shorter, then usual).
I switched from Desktop 1 to Desktop 2 and I switched back from 2 to 1. So there was 5 items of un-group Dolphin, other 3 items and one group of 5 original Dolphin. (So there was 5 items of Dolphin and one group of same items).
And when you try, close 2 or 3 items of Dolphin (not a group) -> Plasma crash.

It is interesting, then if you do this on Desktop 2 and you switch from Desktop 1 to Desktop 2 it is OK. But if you switch from Desktop 3 to Desktop 2, original group will add items, which contains. But you have to activate setting, than taskbar displays only windows from actual desktop.
Comment 3 Dario Andres 2010-02-21 16:20:41 UTC 
- Is this still reproducible on KDE SC 4.4.0 ? Some related bugs were fixed.
Regards
Comment 4 Carth Onasi 2010-02-21 17:44:32 UTC 
It is OK now. Thanks.
