When launching nautilus HEAD, built on 5/20/02 with a bogus commandline
paramater e.g. 'nautilus --foobar', it segfaults upon startup, see attached
backtrace:

Starting program: /gnome/head/INSTALL/bin/nautilus --foobar

Gdk-ERROR **: The program 'nautilus' received an X Window System error.
This probably reflects a bug in the program.
The error was 'BadPixmap (invalid Pixmap parameter)'.
  (Details: serial 5384 error_code 4 request_code 2 minor_code 0)
  (Note to programmers: normally, X errors are reported asynchronously;
   that is, you will receive the error a while after causing it.
   To debug your program, run it with the --sync command line
   option to change this behavior. You can then get a meaningful
   backtrace from your debugger if you break on the gdk_x_error() function.)
aborting...

Program received signal SIGTRAP, Trace/breakpoint trap.
