hi mike,

thanks for the bug report.  to clarify, do you need to
issue an [incr tsdb()] command to trigger the issue,
or does it just happen as part of the batch parsing

it looks to me as if (a) your results include MRSs
(not a bad thing per se :-), and (b) [incr tsdb()] tries
to operate on those MRSs but fails to unserialize.
i would not expect (b) to be part of batch parsing
(but commands like `Browse|Results' or `Trees|
Annotate' should trigger it), and further expect the
unserializing of `simple' MRSs to be enabled by

any more details on how you are running things
will be appreciated ...

cheers, oe
