[GRASS-dev] trying to test error trapping for invalid gisdbase, location, and mapset

[Michael Barton]

My problem is that with some systems, the GUI doesn't pick it up. I'm not
sure how it does pick up the error and go to the message box (some other
kind soul wrote this). I'll dig into it. I wonder if I get a different kind
of error string to trigger things on my Powerbook and G5?
