It is probably safer to check if expired messages exist before
attempting to delete them, assuming that a query in an empty table does
not generate an error. I have added this and commited the change.
Please tell me if you encounter further errors.

Hi Anca,
I think I have further info ...
the crash happens for i = j = 0 ... (2(6495) DBT:dbt_get_refs:
looping ... i=0 (4), j=0(8))
and the reason, i think, is when file has NO data-row ... that is:
file content:
id(int) ...... NO_RETURN
NO_DATA_ROWS
If I add just a return after the table fields definition, it seems to
be ok ...

For this problem with watchers table I can't figure where the problem
is. It would be very helpful if you would print the values for i and j
and send the result.
