-- 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.

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).
