After upgrading a linux server to openssh 6.7, I'm no longer able to connect to it from MS Windows (winswitch 0.12.20). In the server's log I see "fatal: Unable to negotiate a key exchange method [preauth]". I have no trouble connecting to the server via putty.

It seems that this is a twisted-conch issue: ​http://twistedmatrix.com/trac/ticket/7672

However, I assume that even once that's fixed, some work will be required on winswitch's part, too, even if only to create a new build; so opening a ticker here, too.

.desktop files aren't being parsed correctly. Thunderbird is showing incorrectly as "Contacts". It appears only the last section is being processed, not the Desktop Entry section.

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?.

>>> from subprocess import Popen
>>> env = {'GST_PLUGIN_PATH': u'C:\\Program Files (x86)\\WinSwitch\\gstreamer-0.10'}
>>> Popen("notepad", env=env)
