driver's door will not open (unlocked)

[David Kase]

Car: 1990 Coupe Quattro

Problem:  driver's door will not open from inside or outside

The seat belt is not caught in latch.
It feels like both handles (in and out) are operating the latch but the 
door does not budge.
Door locks and unlocks normally (button goes up and down).

Any BTDT's?

Any ideas on how to get the door open?

Thanks,
Dave Kase
feeling a bit like Luke Duke...
