Application: kwin (4.11.17)
KDE Platform Version: 4.14.6
Qt Version: 4.8.6
Operating System: Linux 3.16.7-7-desktop x86_64
Distribution: "openSUSE 13.2 (Harlequin) (x86_64)"

-- Information about the crash:
- What I was doing when the application crashed:
Crash while running Bleachbit 1.6 ... i guess i remove caches file needed for this package...
but, if cache files are in use, bleachbit should not be able to remove them in terms of security and/or system stability ....

The crash can be reproduced sometimes.

-- Backtrace:
Application: KWin (kwin), signal: Bus error

The bleachbit authors are not capable of doing correctly what they want to do and the usage is largely questionable anyway.
As a result, they "accidentally" damage process memory (through shared data caches).
