You're right, the initial value of fluids in threads that are not
spawned from a Guile thread is #f. I think this is a bug, but it's
longstanding behavior, so we can't change it in 2.0 I think (or can
we?).
But anyway, the rest of the code is usually careful to provide a default
value if a fluid is #f, but not so in this case it seems. Thanks for
the report; will fix.
Cheers,
Andy
