Description of problem:
In /usr/share/applications/kde4/backintime-kde4-root.desktop, "Exec=kdesudo -c backintime-kde4-root". But while I remember using kdesudo a while ago (or that might have been kdesu), it certainly isn't on my system now, and `yum search all kdesudo` comes up empty. If I'm wrong and it is out there somewhere, it should be Required by backintime-kde.

Version-Release number of selected component (if applicable):
1.0.28-2.fc19

How reproducible:
Should be quite consistent.

Steps to Reproduce:
1. yum install backintime-kde
2. From Kickoff launcher -> Applications -> Administration -> Back In Time

Actual results:
In ~/.xsession-errors, "Could not find 'kdesudo' executable."

Expected results:
Runs backintime-kde4-root or backintime-kde4 as root, after authentication of some kind.

Additional info:
For some reason, it does require usermode-gtk, even though it doesn't use that here.
Perhaps because when I run backintime-kde4-root as ordinary user, I do get a root authentication popup, and then it does run as root. So, it probably just needs the "kdesudo -c " part removed from the Exec line, and then should work as expected.
Using kdesu instead might be another option.
kdesudo is probably leftover cruft from (k)ubuntu, which does seem to have it, much like the default "~/Ubuntu One" which is still in the recommended excludes, and could go away.
May be indirectly related to Bug #502806, "switch to using PolicyKit".
On a tangent, it would be nice if the menu entries were more clearly labelled by default, so you can tell root from not-root version, and -kde4 from -gnome. The Gnome one in the Administration menu is at least labelled "Back In Time (root)", so I can tell it from the KDE one there. When you get to it by typing "backintime" in the Kickoff search, there's no way of knowing which is which between root and non-root.
