From bug 268873 (KDE SC 4.6.1):
- What I was doing when the application crashed: After trying new plasmoid
(downloaded by assistant) and closing them, plus using new pre-installed
plasmoid, then closing them (Mem, Temp, CPU) I close my kde4 session several
hours after. Give me this crash.

Here using:

KDE 4.7 master
kdelibs commit 8d65adce7b3e2262e464ce989bd0add197f416a3 (Sun May 8 18:18:23 2011 +0200)
kdebase-runtime commit 5ace8a676768fd31f301d71e8f49b6c415d8b844 (Sun May 8 22:11:34 2011 +0200)

It seems I can reproduce the issue
- Go to Add Widgets -> Get New Widgets -> Download New Plasma Widgets
- Install one of them
- Close the window ("Close" button on the bottom right corner)
- Close Plasma ($ kquitapp plasma-desktop)

Plasma crashes with the following backtrace:

plasma-desktop (0.4) on KDE Platform 4.7.00 (4.7.0) using Qt 4.7.3

- What I was doing when the application crashed:

Previously I had opened the plasma "add/remove plasmoid" panel and the install-from-the-web window also. I didn't put any plasmoid onto the desktop or to the panel, though.

While logging out, plasma crashed.

Could you try to reproduce this under KDE 4.8.x with Qt 4.8.x? Since this really looks like a Qt issue if i look at the stacktrace.

See comment #17, waiting for feedback.
Comment 19 Dimitrios Glentadakis 2012-07-17 10:58:25 UTC 
Me, i dont have any more this issue.
Mageia 2, kde 4,8,2
Was specially after having installing a plasmoid script

I didn't see it from a long time, pretty much 100% sure from the time I start using 4.8x series
