New crash information added by DrKonqi

plasma-desktop (0.4) on KDE Platform 4.6.2 (4.6.2) using Qt 4.7.2

- What I was doing when the application crashed:

I'm using Kubuntu 11.04.
At the time of the crash, my screen was locked. A couple of Eclipse windows were open. Kmail was open. Chromium was open.  Firefox was not open, but is installed.

This is far from the first time the crash has occurred. I cannot reproduce this crash at will. Only Plasma-deskop is ever affected by the crash. After the crash happens, my panel moves from the left-hand side of my screen to about 3% of the way from the right-hand side of my screen.

Desktop Effects are enabled. Compositing mode is XRender. I used to be using OpenGL as the compositing mode. This crash still happened then.

I was not experiencing this crash with Kubuntu 10.10. I have not attempted to disable Desktop Effects.

Comment 4 Delete Account 2011-06-04 00:07:03 UTC 
Additional information:

I am *not* using Amarok.
I am running Skype v2.2.0.25, installed from a .deb that I downloaded from Skype's website.
Comment 5 Delete Account 2011-06-04 00:11:23 UTC 
Even more additional information (Last time, I swear!):

I am using the RSSNow Plasmoid. I cannot remember if I have ever experienced this crash when I was not using the RSSNow Plasmoid.
Comment 6 fshaked 2011-06-04 01:00:04 UTC 
I am also using RSSNow plasmoid.
I am not using Skype.
