window decorator crashing due to Spotify on wine

Running Ubuntu 12.04, upgraded from 11.10

To reproduce:
- Install wine and install spotify.
- Launch spotify and move it to a different workspace. Start playing music.
- Go back to your primary workspace. Wait until a spotify ad pops up
-- The ad should have no window borders. Eventually it'll fade away, or you can click it to get rid of it. For a brief moment, window borders will appear around the spotify ad before closing.
-- After the ad closes, the window borders will disappear from all windows.
- Run compiz --replace to get the borders back..

This is what popped up in my terminal window when the crash occurs:

The program 'gtk-window-decorator' received an X Window System error.
This probably reflects a bug in the program.
The error was 'BadWindow (invalid Window parameter)'.
  (Details: serial 20155 error_code 3 request_code 20 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.)
