Hi Beat,

I'm not a programmer, so I could be wrong ;)

If I take a look at bug 246191 it says that plasma crashed because Qt
sent event=0x0 (and that it should be resolved upstream). However, in
this bug I don't see the event=0x0. So why would it be a duplicate?

Best regards,
Jeroen Eeuwes

Comment 7 Beat Wolf 2011-11-22 07:46:34 UTC

while true, if you look at the methods and source code lines called, they are the same. now i might be wrong (closed 110+ bugs yesterday), but i'm pretty sure its the same bug. Or at least that closely related that it can be counted as the same.

But if somebody disagrees, please free to reopen.

- What I was doing when the application crashed:

After work session Plasma just crashes, it is relatively frequent on shutdown. Maybe related to shutdown problems I often have?

New crash information added by DrKonqi

plasma-desktop (0.4) on KDE Platform 4.8.3 (4.8.3) using Qt 4.8.1

- What I was doing when the application crashed:

I was shuting down my computer.

- Unusual behavior I noticed:

Before the crash I was tring to download magnet links. They created some plasma tasks. Several times I tried to drag them as a widget and then returned them back to icon in taskbar. They were completely broken. Sometimes these widgets got zero size, sometimes they were drawn out of their frame.

After some time I gave up and cancel these tasks. Then I turned my computer down and plasma crashed.
