I am using your deb repository on a Debian 6.0.6 system and just upgraded xpra to v0.8.1. Xvfb got removed, because it was not depended on anymore. xserver-xorg-input-void and xserver-xorg-video-dummy were installed to fulfill dependencies.

Attempting to start xpra:

$ xpra start :999
cannot load vpx codec: /usr/lib/python2.6/dist-packages/xpra/vpx/codec.so: undefined symbol: vpx_codec_enc_config_default
No handlers could be found for logger "xpra.sound.gstreamer_util"
Entering daemon mode; any further errors will be reported to:
  /home/user/.xpra/Squeezy-999.log
$ cat ~/.xpra/Squeezy-999.log
Error starting Xvfb: [Errno 2] No such file or directory
2013-02-05 14:00:13,957 removing socket /home/user/.xpra/Squeezy-999

I installed xvfb manually and now xpra works like it did before, but since the depencies changed, I believe, that´s not the intended behaviour.
