I am running linuxmint olivia amd64 and have a try xpra for a first time. apt-get install xpra installs me 0.10.1 version.
According to minimal instructions on first console i try to run
xpra start :100 --start-child=xterm --no-daemon --no-notifications --no-pulseaudio
and xpra attach :100
on second console that quickly ends with
xpra attach :100 xpra client version 0.10.1 2013-08-29 10:30:58,477 No OpenGL_accelerate module loaded: No module named OpenGL_accelerate 2013-08-29 10:30:58,635 OpenGL Version: 3.3.0 NVIDIA 313.30 2013-08-29 10:30:58,659 GL Extension GL_ARB_shader_objects available 2013-08-29 10:30:58,683 GL Extension GL_ARB_framebuffer_object available 2013-08-29 10:30:58,685 GL Extension GL_ARB_fragment_program available 2013-08-29 10:30:58,686 GL Extension GL_ARB_texture_rectangle available 2013-08-29 10:30:58,686 GL Extension GL_ARB_vertex_program available 2013-08-29 10:30:58,876 server requested disconnect: invalid packet format 2013-08-29 10:30:58,877 connection closed after 1 packets received (55 bytes) and 1 packets sent (25K bytes) 2013-08-29 10:30:58,978 Connection lost
on a server side i see an exception

Hmmm, that's going to be difficult to diagnose.
Somehow the initial packet gets encoded but fails to decode..
And since logging network packets was slowing things down too much, I have removed it. So, to see the actual packet contents, you will have to use "-z 0" to turn off decompression, connect to a tcp socket ("xpra start --bind-tcp" + "xpra attach tcp:HOST:port") and use tcpdump or ngrep to capture it.
The encoder code has not changed at all in a very long time. But the amount of data we include in the hello packet has, so downgrading to 0.9.x may help.
tcpdump log
ok.
xpra start :100 --start-child=xterm --no-daemon --no-notifications --no-pulseaudio -z 0 --bind-tcp 127.0.0.1:8888
xpra attach tcp:127.0.0.1:8888
tcpdump -w /tmp/xpra.pcap -s 2048 -i lo port 8888
and xpra.pcap​ in attachment
(only just saw your tcpdump as I was writing this) I've tried reproducing the bug using the packet string from the bug, but the packet string sample isn't long enough:

Python and strings is a terrible mess...
I suspect that this has something to do with unicode characters in the hello packet, can you try temporarily setting your name (as found in /etc/passwd to a pure ascii string instead? Or even just as a newly created test user (say "test"). And anything else in your `env` that has non-ascii characters. Does this fix things?
I have changed user name to latin only chars and it fixes an issue. Is it possible to override it with some environment variable instead of changing username in /etc/passwd ?
Is it possible to override it with some environment variable instead of changing username in /etc/passwd ?
No, we get it from the system's pwd API.
But I will cook up a fix today and release 0.10.2
Thanks in advance!
I had done some work already on strings and unicode to try to revive the python3/gtk3 client support, see r4205, r4206, r4207 and r4209 (it was a bit messy as I messed up the commits..)
r4237 works for me even after changing my name in /etc/passwd
If you can, please confirm that r4237 (for trunk) or (r4238 for v0.10.x branch) fixes things for you too. I will release 0.10.2 with the fix asap.
What is odd is that I get a different error from the one you posted, mine is client side:

I confirm it works now just fine.
Closing. Thanks for your help!
v0.10.2 has been released with the fix, it is available in binary packages will follow shortly.
