Hi Shaya,
this observation might be related to your problem: I had a problem with
the dcopserver during KDE startup. I'm working on a modified KNOPPIX
4.0.2 with a few Debian-Updates and some additional Unionfs-Branches.
At some point KDE didn't start, giving a message along the lines of:

  The message returned by the system was:

  Could not read network connection /home/username/DCOPserver_hostname__0

  Please check that the "dcopserver" program is running.


In a failsafe-session the dcopserver said "ICE Connection rejected!",
after kdeinit tried to talk to it. The permissions on all relevant files
in /tmp and ~/ were ok (according to 'ls').
If I started KDE as root dcopserver worked just fine. I couldn't make
out any files that had unionfs-related permission problems. But my
suspicion is that just this is the cause.
Imho KDE is a bit too complex as a debugging tool.

All this was happening using several unionfs-snapshots since
snapshot-20051006-0924 up to 1.1.0 - I haven't tried earlier versions.
And this was happening after I fiddled with the unionfs-branches.
The usage/omission of delete=whitout made no difference too...

The solution for me was to re-order some of the ro-unionfs-branches and
to avoid overlapping directory structures in the branches.
=> Systems with several branches behave less predictable (wrt
permissions) the more entangled the file systems are... This doesn't
seem to be a new observation. ;-)

Cheers,
Birger
