[intrepid] kde crashing on changing background

[Gunni]

When trying to change the background in kde4 or adding a plasmoid kde crashes completely and throws me to login screen.
Attached debug info for the crash on changing background picture.

Thank you for taking the time to report this bug and helping to make Ubuntu better.
This bug did not have a package associated with it, which is important for ensuring that it gets looked at by the proper developers. You can learn more about finding the right package at https://wiki.ubuntu.com/Bugs/FindRightPackage.
I have classified this bug as a bug in kde4libs.

According to the upstream report your crash is in the X driver for your video card. (Plasma can't crash X directly, but it can expose bugs in the video drivers.)

Just tested a bit further.
Disabling triplebuffer seems to solve the crash, so you seem to be right. Had that in my config since long time, as i read it should improve performance on nvidia cards (the old known issue, that should be gone now with actual drivers.)
But maybe that helps someone finding this bug report.
