Error Reading Locks

Using 1.0 with DbFileSystem, SimpleDbPersistenceManager, on MSSQL.

I don't know what is exactly causing this error, but sometimes after a
session is closed, a record where FSENTRY_NAME='locks' in the
[workspace]_FSENTRY table persists.  The next time a session is open I
receive the following stack trace.  Should this 'locks' record be there?
If so, is there a bug in the data from the field 'FSENTRY_DATA'?

Any ideas?

Thanks
