Public bug reported:
When the software-center cache files located @ /var/cache/software-
center/xapian are deleted the utility crashes after a few seconds when
opening. No crash report is generated and no system error report is
triggered.
A reinstall fixes the issue: sudo apt-get install --reinstall software-
center
Expectation:
==
Since we are taking about cache files making the application crash I believe
this is a bug, cache files shouldn't be depended on and be regenerated if they
are unavailable from the cache directory.
My System
==

applied to the system, some package info is below
