Why?
I've just tried it with the same versions and I cannot reproduce your problem. I can connect just fine via ssh, before and after upgrading the server session to 0.5.3.

You may be able to workaround the issue by using:
xpra --socket-dir="" --ssh="ssh -p2202" attach ssh:remotehost:100
(but sine I do not understand the problem.. this is just a wild guess)

Why does your system try to run the environment variable as if it was a command.. This is what xpra should execute in your case:
ssh -p 2202 -T $rhost XPRA_SOCKET_DIR=~/.xpra .xpra/run-xpra _proxy :100
Can you try running this by hand? It won't work as an xpra client, but do you get the same error message from ssh?

Here's something a little easier to understand that you can try:
ssh -T $YOURHOST XYZ=1 "env | grep XYZ"
You should see: "XYZ=1"
And if you use an invalid command, it does print that command's name and not the environment setting:
ssh -T $YOURHOST XYZ=1 invalid_foo
bash: invalid_foo: command not found

The only other option for debugging your problem is to post:
xpra -d all attach (...)
Please also post your /etc/xpra/xpra.conf (and ~/.xpra/xpra.conf if you have created one)

Hope this helps!
