Even now you can probably (not tried) catch the SystemExit
exception and prevent the program from aborting.
Do you think raising SystemExit like

    raise SystemExit("error while writing file: permission denied")

would be good enough.  The GUI frontend could catch SystemExit,
check whether the associated value is a string, and then display
this string in an error message box.

What do you think?
