strange nhibernate + linq + mysql exception

I'm hitting a strange error when running a query in nhibernate using linq.

If I run the query in directly in mysql, everything works. If I rerun the linq query, I get no error, but only the id field (a string) is fetched. If I run the query many times, sometimes the first row is fetched correctly...

The only thing my google-fu found was this mysql bug, but I cannot see how they are related.

EDIT: It seems related to a varbinary(128) field I have in my database. If I remove this mapping, everything works again. I'm mapping this to a byte[] field in my class.

EDIT: I'm using NHibernate 2.1.2.4000 NHibernate.Linq 1.1.0.1001 (the newest GA versions), and I've tried with MySql Connector 6.1.2 and 6.2.4 (6.3.5 failed to install for some reason)

Has anyone encountered this error before?

I found the error. It's a NHibernate/MySql bug where it throws if the binary field is empty.
