[winswitch] Trouble with xpra 0.10.0

I just upgraded both my server and client to xpra 0.10.0. Both my server
and client are running 64-bit Ubuntu 12.04. My client is running KDE, and
it was running 0.9.x with no problems.

Since upgrading, I've had a lot of problems, such as:
- Windows not repainting at all (get just a frame). Refresh generally
clears this up until it happens again.
- Windows partially repainting (sometime a narrow band shows the desktop
background, sometimes half the window is blank white, sometimes half the
window is a smear of green). Again refresh clears it up for a while.
- Lots of random client side shutdowns. (Bringing up the Session Info
window is almost guaranteed to cause the client to abort.)
- When I start xpra, all windows are moved to desktop #1.
- Lots of focus problems. (Typically have to click the desktop then into
the window that needs focus.)

So something seems to be fundamentally wrong.

I do see one error message on the client as I attach:

On one instance of the client side abort (in this case, it happened when I
tried to open the Session Info window), I saw:

The program 'Xpra' 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 7628 error_code 9 request_code 137 minor_code 4)
  (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.)

Any suggestions? Anything else I can provide to help narrow this down?
