Bug#616510: kdm or xserver crashes intermittently but often when interacting with screen saver unlock dialog
Package: kdm
Version: 4:4.4.5-8
Severity: important
Sorry about the broad subject. I'll describe what happens, maybe someone can help me work out where it should be reported.
I got frequent crashes when the screen saver is running and I interact with the unlock dialog.
This can happen in a resume from suspend or hibernate, but just now I clicked cancel on the unlock dialog and the xsession crashed. Because this causes data loss in open applications, I mark this important.
The bug has been happening for two weeks, more or less.
The kdm log reports segmentation faults so I report it against kdm first.
It's a laptop with intel graphics.
The kernel is sidux.
