software-center crashes on startup with X error

When trying to launch software-center I get:

(software-center:11090): Gdk-ERROR **: The program 'software-center' received an X Window System error.
This probably reflects a bug in the program.
The error was 'BadDrawable (invalid Pixmap or Window parameter)'.
  (Details: serial 1186 error_code 9 request_code 62 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 GDK_SYNCHRONIZE environment
   variable to change this behavior. You can then get a meaningful
   backtrace from your debugger if you break on the gdk_x_error() function.)
Trace/breakpoint trap

Running Gnome 3.8 under 13.04, software-center seemed to run fine in Unity under 12.10.
