I just tested this applied to trunk and get a crash on the communitymx test
page. Loads of details below, let me know if there's anything else I can
provide. The system is Ubuntu 9.10, x86, without any major customizations.
Desktop effects are enabled.

Shortly after the page begins to load, I get a XError and Segfault.


****** Console Output ******

The program 'GtkLauncher' received an X Window System error.
This probably reflects a bug in the program.

The error was 'BadValue (integer parameter out of range for operation)'.
  (Details: serial 32806 error_code 2 request_code 139 minor_code 3)
  (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.)

******* Backtrace from GDB ********

Program received signal SIGSEGV, Segmentation fault.
