Comment 20 for bug 264368

Gdk-ERROR **: The program 'totem' received an X Window System error.
This probably reflects a bug in the program.
The error was 'BadAlloc (insufficient resources for operation)'.
  (Details: serial 91 error_code 11 request_code 140 minor_code 19)
  (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.)

This is simply an out-of-memory error. You might be able to free up more video memory by fiddling with your VideoRam or LinearAlloc settings in xorg.conf, but really Totem just needs to handle this error condition more gracefully. If you're using XAA acceleration, you may find switching to EXA to be helpful.
