Bug Description

[Impact] Software center is force closing (Quantal). Receiving an apport error message that Software center crashed but it stays open (Precise).

[Test Case] Simply start software center with reviews enabled. If you had them enabled before this bug also comes up when disabling reviews.

This is also so we can see if this drops off after the SRU.

[Regression Potential] Failing to repair the DB is possible.
