I finally isolated the problem.
If a user is not in any group, so sql-group is null, FR will crash in 
some time, not immediately.

I solved adding a UNION SELECT 'NOGROUP' As GroupName FROM usergroup' to 
groupcheck query.
Anyway, it would be better correcting it in the code, it may cause some 
other kind of problem.
