Application that crashed: plasma-desktop Version of the application: 0.3 KDE Version: 4.3.4 (KDE 4.3.4) Qt Version: 4.5.2 Operating System: Linux 2.6.31-16-generic x86_64 Distribution: Ubuntu 9.10 What I was doing when the application crashed: I experience rather regularly crashes of plasma desktop. Sometimes, the applet props up without me doing anything particular on the desktop; but I can often reproduce it at activating the dashboard. -- Backtrace: Application: Plasma Workspace (kdeinit4), signal: Segmentation fault The current source language is "auto; currently c".

*** This bug has been marked as a duplicate of bug 201620 ***
And how would this be 'resolved'? The last post in the dup (201620) was "@Quinton: try updating to Qt4.5.2. Thanks" when what I use *is* 4.5.2?
it has been marked as a upstream bug, which means it's a Qt bug and not a plasma bug. So this bug is not tracked in the plasma bugtracker.

So this bug is not tracked in the plasma bugtracker. Ah, yes. But 'resolved' is misleading. So I need to file it with Qt? Uwe
you should. but check first if there was a already closed bugreport (or an open one). if you can then post the link to that bugreport here that would be perfect. thank you
http://bugreports.qt.nokia.com/browse/QTBUG-6924 is the bug that I filed. As it is pointed out there, they need more info. Some small compilable code is needed to demonstrate the problem. Maybe someone with more developing background than me can help out?
