Is this properly a Fedora or an upstream issue?
If the KDE/Konqueror code upstream contains prejudice against operation
as root, then Fedora has no finger in this pie: it simply packaged the
code. The "allow/disallow root" argument belongs upstream; it is not
a Fedora issue.
If Fedora has modified the upstream code to create this aversion to run
as root, then there are two questions:
1. Is it approprate to do this? This thread already contains enough
comments to strongly suggest there will be no concensus about this.
2. Has this been done in a thoughtful way? It may be an appropriate
default setting (avoids risks Fedora thinks users may not expect or
understand), but it should be possible to modify this default so root
operation of Konqueror is possible.
If one builds Konqueror from upstream source, does it balk when invoked
as root? If it does, argue upstream. If it does not, look further into
what Fedora has done, but you now have a Konqueror you can use as root.
