xpra isn't working in 0.12.20 Server is Ubuntu 12.04 64bit, client is Windows 7 64bit Both run WinSwitch? 0.12.20. Server's xpra is v0.14.6-2

Part of server log:

Traceback (most recent call last):

I've downgraded xpra to 0.13.9-1 and that's working.

xpra hasn't been working the last few updates.
Checked the server log, and it showed:

[EE] 2012/10/09 19:00:14 WinSwitchServer.assign_virt_utils() failed to load xpra, make sure it is installed: No module named xpra.dotxpra

Fixed that with sudo ln -s /usr/lib/xpra /usr/lib/pyshared/python2.7/ but I still can't start an xpra session.

This was with: Server: Ubuntu 12.04 64bit, Client: Windows 7 64bit Both are running v0.12.16

$ dpkg -l winswitch xpra
ii  winswitch                                  0.12.16-1
ii  xpra                                       0.6.0-5

I updated from the PPA last week and noticed the html5 client no longer works. I just get an empty white screen instead of windows loading. I was able to fix this by copying the /usr/share/xpra/www folder from a system that had a prior working install on it.
