Bug 303312

Application: ksmserver (0.4)
KDE Platform Version: 4.8.4 (4.8.4) (Compiled from sources)
Qt Version: 4.8.1
Operating System: Linux 3.2.0-26-generic x86_64
Distribution: Ubuntu 12.04 LTS

-- Information about the crash:
- What I was doing when the application crashed:

When running some progs, and starting bleachbit, additionally, KDE crashes.

Is it not possible to run more than one KDE prog at the time given?

Or to check croiss-relation bewtween progs before anou ncing a new KDE version?

Why these questions?

Very simple: as KDE will die, if is not better than others... and there are good ones... mint, gnome(?)

The crash can be reproduced some of the time.

-- Backtrace:
Application: Der KDE-Sitzungsmanager (kdeinit4), signal: Bus error
