I have followed this discussion as I have the same problem on a Fedora10 box 
with KDE 4.3.2 fully updated:

When I change the command line in the program page in the Dolphin desktop file 
to:
kdesu 'dolphin %i -caption "%c" %u'
I get a request for root password and then Dolphin runs as root. However, when 
trying to invoke kwrite on any file I get:
KDEInit kunde inte starta "/usr/bin/kwrite" which translates to KDEInit could 
not start "/usr/bin/kwrite"

Starting Dolphin from a root shell when logged in as another user gives the same 
result with some additional output after Dolphin is closed:
[root at oden ~]# dolphin
[root at oden ~]# kDebugStream called after destruction (from void 
KDirWatchPrivate::removeEntry(KDirWatch*, KDirWatchPrivate::Entry*, 
KDirWatchPrivate::Entry*) file 
/builddir/build/BUILD/kdelibs-4.3.2/kio/kio/kdirwatch.cpp line 901)
Cancelled INotify (fd 10, 1) for "/root/.local/share"

[root at oden ~]#

I hope this might help nailing down the problem
