Comment 23 for bug 187918

Philippe,

Does KDE 4.0 work for you? This bug was originally about KDE 4.0, but it seems to have been fixed.

Using:
dbus 1.1.20-1ubuntu2
dbus-x11 1.1.20-1ubuntu2
hal 0.5.11~rc2-ubuntu8.1
kubuntu-kde4-desktop 0.14
libdbus-1-3 1.1.20-1ubuntu2
linux-headers-generic 2.6.24.19.21
kde4-core 3.3
kwin-kde4 4:4.0.3-0ubuntu2
and all other kde4 packages I checked (inc. kdm-kde4) are 4:4.0.3-0ubuntu2, except kde4graphics-dev, kdenetwork-kde4, kdesudo-kde4 (which are ubuntu1), and kdeutils-kde4 (which is ubuntu4)

And actually, the solution you mention is mine.

To see if this is the same bug, I suggest you try this:
$ sudo touch $HOME/foobar
$ ls ~/foobar
If the file is there, it's the same problem. If you get an error on the first command (permission denied), then I don't think your problem is related.

Do you remote mount your home directory? This appears to be mostly a problem of root not being able to write to directories mounted by users using automount/autofs.
