[Bug 1730877] [NEW] dolphin does not start as root

[wolf]

Public bug reported:

Package: kubuntu-17.10-desktop-amd64.iso
step 1:
Starting dolphin from the menu fails - kdesu starts to accept password, but then Dolphin does not open.

three attempts to start dolphin from the command line:
step 2: 
wolf at wolf-desktop:~$ kdesu dolphin
kdesu: command not found
as per man file, this is because kdesu is not in the path

step 3:
wolf at wolf-desktop:~$ /usr/lib/kde4/libexec/kdesu dolphin
Executing Dolphin as root is not possible.
/usr/lib/kde4/libexec/kdesu is a link that ultimately points to kdesudo

step 4:
wolf at wolf-desktop:~$ /usr/bin/kdesudo dolphin
QInotifyFileSystemWatcherEngine::addPaths: inotify_add_watch failed: No such file or directory
QFileSystemWatcher: failed to add paths: /home/wolf/.config/ibus/bus
Bus::open: Can not get ibus-daemon's address. 
IBusInputContext::createInputContext: no connection to ibus-daemon 
Executing Dolphin as root is not possible.

Here I gave up, as the likely next steps are beyond my ability.

Other observations:
Since my system contains about a dozen partitions, I need to manually modify fstab and /media to define which partitions are mounted at start-up, and which are mounted only upon request. I do this by assigning unique labels to each partition, since UUID's are not human-readable. Since a label can be assigned to 17.10 only from another installation of 17.10 and not from an older installation such as e.g. 16.4, because of some code changes needed for e2label, I have also tried to directly copy the changes to fstab and /media from another installation. This copying action made the whole 17.10 unusable - the commandline is available, but the x-system needs starting manually, and there is also no network access.
