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.
