[Sasa Paporovic]

This crasher happends during a system run of several hours with not specific doing on the system.

Steps to reproduce:

Unfortunally it is not possible to give a reliable reproducing procedure.
Run the sytem for several hours.

Additional:

clamtk was running called by gksu a recursive search for malware through the filesystem.
No other GUI- or user started program was running.

Additional2:

This is propably a regression of a already fixed bug in Ubuntu11.10 Oneiric.
