@Eduard & @sbeattie: Can you try changing the line from:
$cmd .= " -extension XFIXES";

to the following combinations, and see if one of them resolves the issue. It would be good to get this fixes prior to the next upload:
$cmd .= " -clear_keys";
$cmd .= " -repeat";
$cmd .= " -repeat -clear_keys";

Status in “vnc4” package in Ubuntu: Fix Committed

Bug description:
Trying to start vnc4server via "vnc4server -geometry 1400x990 :1" fails always; the .vnc/$HOST:1.log leads off with

  Unrecognized option: -extension

Doing an strace on the vnc4server binary shows that it's trying to execute Xvnc4 like so:

  Xvnc4 :1 -desktop "denisovich:1 (steve)" -auth /home/steve/.Xauthority -geometry "1400x990" -depth 16 -rfbwait 30000 -rfbauth /home/steve/.vnc/passwd -rfbport 5901 -pn -extension XFIXES -fp "/usr/X11R6/lib/X11/fonts/Type1/,/usr/X11R6/lib/X11/fonts/Speedo/,/usr/X11R6/lib/X11/fonts/misc/,/usr/X11R6/lib/X11/fonts/75dpi/,/usr/X11R6/lib/X11/fonts/100dpi/,/usr/share/fonts/X11/misc/,/usr/share/fonts/X11/Type1/,/usr/share/fonts/X11/75dpi/,/usr/share/fonts/X11/100dpi/" -co /etc/X11/rgb

but that Xvnc4 no longer recognizes the -extension argument. This was working with vnc4 4.1.1+xorg1.0.2-0ubuntu7 in lucid.
