[winswitch] exiting winswitch or xpra application crashes server desktop

[basd]

New development that may be related to linux kernel 4.0.

On my openSuSE 13.2 server, which I upgraded to kernel 4.0.x, when I "quit" the winswitch tray, the
KDE desktop crashes.  The same happens it if quit a remote xpra application session. (This seems to
be the "last" running application session, if I have more than one open).  Only crashes if I close
the application, I can pass it back to the server & no crash until I close it.

To recover the server, <ctrl><alt><del> -- computer reboots to a console session.  Then I log in as
root, run "reboot" and it recovers to the normal user desktop.

So, it seems as though winswitch/xpra are messing with the main server "x" session.

Not so good if I am far away from the server and crash it remotely ...

Still trying to figure out why I can't launch desktop sessions on my openSuSE 13.2 server (only xpra
applications); whereas on myopenSuSE 13.1 server, I can ONLY open desktop sessions and no xpra.  I
have started studying the winswitch python code, but I am a long way from understanding it in a
meaningful way.

Thanks!
