RE: Moved position out of bounds error

My original message mentioned this as being a problem during database
creation. However, it occurs during database updates as well. The stack
trace I see is as follows.

Thanks,
Arjav

Subject: Moved position out of bounds error

Hi,

	I'm using Mckoi 1.0.3 on 64-bit Linux and sometimes get an error
when creating a database. The database creation works most of the time,
but occasionally it will fail and give me the following stack trace. I
was hoping someone could let me know what was going on.

Thanks,
Arjav
