This is complicated because dumpcap uses stderr to pipe error messages 
to Wireshark, but they have to be in a special format (see source code 
comment starting on line 3790 of dumpcap.c in the latest SVN).  The 
sync_pipe_errmsg_to_parent() function might help you feed an error to 
Wireshark, which in theory it will pass through to the user in the GUI.
