[Zope] Bizarre new problem...

[Chris McDonough]

I suspect this is coming from MySQLdb.  From the Python DB-API spec:

OperationalError 
 Exception raised for errors that are related to the database's
 operation and not necessarily under the control of the
 programmer, e.g. an unexpected disconnect occurs, the data
 source name is not found, a transaction could not be processed,
 a memory allocation error occurred during processing, etc. It must
 be a subclass of DatabaseError. 

.frm files seem to be table data containers for MySQL.  You should try
operating on your database outside of Zope to see if you can reproduce
the problem.
