Hi,

The plugin also outputs some debugging information to the console,
maybe this will be more helpful:


The program 'GoogleTalkPlugin' received an X Window System error.
This probably reflects a bug in the program.
The error was 'BadAtom (invalid Atom parameter)'.
  (Details: serial 503 error_code 5 request_code 20 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.)


Cheers,
Jaros│aw Rzeszˇtko
