Public bug reported: This is the output to stderr:

This probably reflects a bug in the program. The error was 'BadWindow (invalid Window parameter)'. (Details: serial 348072 error_code 3 request_code 20 (core protocol) 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 GDK_SYNCHRONIZE environment variable to change this behavior. You can then get a meaningful backtrace from your debugger if you break on the gdk_x_error() function.)
