totem crashes on startup with signal 5 in _XError()

Binary package hint: totem

When I launch totem, the window appears for a second, then closes. Running from the terminal produces the following:

---
[01:42:05] robert@fnord - ~ $ totem

Gdk-ERROR **: The program 'totem' received an X Window System error.
This probably reflects a bug in the program.
The error was 'BadMatch (invalid parameter attributes)'.
  (Details: serial 979 error_code 8 request_code 1 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.)
aborting...
Trace/breakpoint trap (core dumped)
