Maybe Off-Topic: remote Perl Gtk2 via ssh

[Daniel Kasak <dan enthalpy homelinux org>]

Hi all.

I'm trying to use ssh's 'forward X11' feature to run a Perl Gtk2 app on 
the server at work and display it here at home.
I can run a number of apps this way, such as xclock and galctool ( which 
is a gtk2 app ).
However I can't run any Perl Gtk2 apps this way. I get:

The program 'test.pl' received an X Window System error.
This probably reflects a bug in the program.
The error was 'BadWindow (invalid Window parameter)'.
 (Details: serial 61 error_code 3 request_code 38 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.)

Is there any reason why I shouldn't be able to forward Perl Gtk2 apps 
via ssh? It seems a little strange that I can run some gtk2 apps but not 
this one.
