Bug Description

Binary package hint: nspluginwrapper

My gdm desktop froze shortly after switching from the browser to evolution with the only indication of an issue in my dmesg output:

This is the second time my desktop froze in the last few days. I was able to switch to a console and save the dmesg output. Please let me know how to more precisely identify the reason for a frozen desktop.

Note the mouse pointer was still moving but other than that all other desktop output (inkl. time which is displayed in seconds) and system monitor output in the panel were frozen.

Anyway, I'm sure the segfaults of the flash player should be reported.
