using nouveau on NV17 kills the KDE VNC server

I connect to a distant desktop using VNC. The environment is KDE and I use its
VNC server, krfb.

The adapter is as following:

  01:00.0 VGA compatible controller: nVidia Corporation NV17 [GeForce4 420 Go]
(rev a3)

Using nv, I used to connect and disconnect several times a day.

Using nouveau, I can only connect once. The second time, vncviewer fails.

First time

I only close the vncviewer window between the tries.

I tried "-log *:stdout:100" to get maximum information but nothing more is
printed.

Nothing is printed in syslog nor Xorg.0.log at the moment I try.

Last ouput of syslog is:

I have a nice .xsession-errors that I'll attach afterwards.
