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:

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

Xming is failing to launch because one of the PATH variables is unicode and Python 2.7 doesn't accept unicode there.

Fix would be to add for k, v in env.items(): env[k] = str(v) to exec_nopipe in winswitch/util/process_util.py

I've tested this in a Python shell since I'm not set up to build WinSwitch?.

>>> env = {'GST_PLUGIN_PATH': u'C:\\Program Files (x86)\\WinSwitch\\gstreamer-0.10'}
