Removing a clutter-gtkmm widget causes X Window System error

[Dirk Vanden Boer <dirk vdb gmail com>]

Hi,

Whenever I try to remove a clutter-gtkmm Embed widget from my
application it causes an X Window System error which exits my program:

The program './test' received an X Window System error.
This probably reflects a bug in the program.
The error was 'BadWindow (invalid Window parameter)'.
  (Details: serial 68 error_code 3 request_code 10 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.)

I made a small test case that reproduces the problem: http://pastebin.ca/1480549
Compile with: g++ `pkg-config --cflags --libs clutter-gtkmm-0.9`
main.cpp -o test

Am I doing something wron or is this a clutter bug?

Best regards,
Dirk
