[winswitch] Failed to encode packet error using xpra-0.8.3

[Douglas Doole]

I just updated my Ubuntu systems (client and server are both running
Precise) to xpra-0.8.3-1. Things were working fine prior to the update. (I
was using 0.8.1 on both client and server.)

I upgraded the display at the server with no problems (xpra upgrade :1).

When I attempt to connect, however, I get a "Failed to encode packet"
error: (I pruned this a bit so it fits in the email)

xpra attach ssh:reorx:1
