	:-) I would be surprised if on a recent install there were any
berkeleydb files created and/or opened anyway, IIRC I removed several
failure paths here for new profile creation in 3.5.

	Is it possible that we are firing that lot up, only then to discover
that in fact there is no .db file to load or somesuch ? perhaps there
are some instances where checking the db doesn't exist before
activiating whatever libdb linking component uses it might help (?)

	Otherwise, the mind boggles - what is the purpose of that db ? is it
ever written to ? :-) if not, why ... ? :-)
