How long does it take to return that error?  Sometimes the unlock takes
a while, and if the program uses a very short timeout, this could
happen.  I'm not sure what d-feet uses offhand.  The other possibility
of course is that ModemManager has a bug.  From the trace you've got
there, it doesn't appear that MM should be rechecking the PIN state like
that.  Any chance you can poke around in mm-generic-gsm.c where it
checks the pin state and see what's going on?
