I'm glad you sorted your problem, but the above certainly does sound like a
bug - the dicts.dat file should only be written when a new module is added
to the dir, not when an existing module is imported.  If you or anyone feels
like digging into this, feel free to ask for help and/or send me a patch
which addresses it.

Cheers,
