I realize it has been a while, but what backend were you using
and do you have a simple test case that I can run?

Also you are a bit of an edge case. You shouldn't be deleting items.
Retiring them is the preferred method to keep referential integrity.

Why did you want to delete the message entry? Also note that message
content/text isn't kept in the db, it's in a disk file under the
tracker's db/file directory IIRC. So if you had a password or something
submitted deleting the message doesn't delete the message content.
