Xpra: Ticket #322: window.py:316 do_get_property_client_contents: AttributeError

When I use winswitch (with Xpra) to run the 3D game 'openarena' remotely, i got the error report from winswitch server side,

"window.py:316 do_get_property_client_contents: AttributeError:'NoneType' object has no attribute 'get_property"

Is this related to #264 you mentioned which is regarding the fullscreen problem?

I don't think this is related, I think I hit a similar error yesterday but it didn't look fatal in my case (mine was in the screenshot code). Do you have a more complete stacktrace? Or can you give me the debug log (run with -d all) extract of just before and after this happens?

i don't know how to manage xpra under winswitch. So, I just run xpra with -d all itself. The error log file is attached.

That's odd, I can't see any AttributeErrors in there.

I do think we're not far off being able to support games (graphics at least, the mouse will be a bit more tricky) - FWIW, the automated tests run nexuiz demo, etc..

some of the games can work is enough for me:) I also find that supertuxkart can work~

OK, well without details, I cannot fix this error.

The one I had seen with screenshots is fixed in r3129
