Bugzilla Interview Question:

Why do I get bizarre errors when trying to submit data, particularly problems with groupset?

If you're sure your MySQL parameters are correct, you might want turn "strictvaluechecks" OFF in editparams.cgi. If you have "usebugsentry" set "On", you also cannot submit a bug as readable by more than one group with "strictvaluechecks" ON.
