> Greetings.
> I have come across a peculiar bug which always happens when I execute
> commands following the order specified in the attached file [^bug.txt]
> Basically, it ends up not only creating lots of files in order to store just
> one entry, but also gives erroneous output to certain queries.
> I think it is related to the "compute stats" command.
> Hope this helps
