-- Information about the crash:
Title says everything..
Most probably there is already a report of this bug but I cannot be 100% sure and the dump shown me three stars of usefulness. That`s why I`m reporting it.

The crash can be reproduced some of the time.

 -- Backtrace:
Application: Plasma Workspace (kdeinit4), signal: Aborted
