[winswitch] Downgrading xpra

[Wolfram Humann]

I've been using xpra 1.0.x before on an older workstation and 2.5.3 on the
current workstation. My impression is that the old version was running
smoother and had less network problems. That may be true or not!! I just
wanted to try it out. So I yum remove-ed the current version and some
dependencies and tried
sudo yum install xpra-1.0.13
and got

 You could try using --skip-broken to work around the problem
 You could try running: rpm -Va --nofiles --nodigest

What can I do?
