When Evolutions mailer component is first time activated after Evolution was newly startet causes an X Window System error.

The program 'evolution' received an X Window System error.
This probably reflects a bug in the program.
The error was 'BadRequest (invalid request code or no such operation)'.
  (Details: serial 3033 error_code 1 request_code 0 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.)

All this happens while while/before drawing the small month view calendar at the bottom left, the big day view in the center and the task list at the right. 

I'm using Evolution 2.30.3-5 Debian package.

This bug is related to Bug #641152. The deadlock happend at exactly the time and with exactly the conditions as this reported bug. Since I've updated Xorg and the Nvidia drivers, the deadlock does not happen any more. Therefore I could investigate the problem in more detail.
