Ciao Radim,
could you fix that? Not sure what's missing...
Thanks
Markus
The problem is that G_fatal_error() must be used to get an error message
formated for GUI. Unfortunately G_fatal_error() calls exit() and G_parser()
must not exit. G_set_error_routine() does not help because in that case
G_fatal_error() prints nothing.
