Whilst I appreciate that it is the equivalent of a Sledgehammer,
Nepomuk has no tools to perform garbage collection, integrity
verification and other methods which could render it's database usable
again. Removing it is the only known method at this time of fixing
those issues.

I agree that it is not optimal. Users are always warned that
Tags/Ratings/etc will be lost as a result of removing the database.

However, until tools are offered by the applications or Nepomuk
itself, removing the database will continue to be the only way to
absolutely assure that no problems exist inside the Nepomuk database
which could be the cause of issues in applications which use it.
