I can almost guarantee that one of the parameters to one of the
functions on this stack trace is NULL. Every time I've seen one of
these problems (and we've had a couple with pgAdmin3), the problem is
almost always that. The best way to tell is to step your way through
the program and print out the parameters before they get passed. I
don't know how familiar you are with gdb, but maybe you can give this a
shot. Or maybe you can give Andreas access to your server to look at
it. :-)
