Description of problem: Configuring arts to "Exchange security and reference
info over the X11 server" in the KDE Control Panel (kcontrol) hoses the KDE
session: mcop cannot find an implementation Arts::X11GlobalComm and knotify
enters a loop reporting that ... knotify crashed. A new instance of knotify pops
up, starting at <1> and going up to <36> before I terminated the session, every
few seconds.

Version-Release number of selected component (if applicable): 3.1-11

How reproducible: Configure runlevel 3 and switchdesk to kde, then startx.
Please note I used 'startx -- -dpi 100x100 -nolisten tcp'.

Steps to Reproduce:
1. startx into the KDE session
2. Go into KDE Control Center
3. Pick sound, configure to "Exchange security and reference info over the X11
   server"
4. Exit KDE session
5. Try startx again
    
Actual results: Knotify reports that an application crashed (first instance) and
then reports that knotify crashed, looping over itself every few seconds.

Expected results: Normal start of sessions, possibly without sound.

Additional info: I traced the problem to MCOP being unable to find an
implementation for Arts::X11GlobalComm. It looks for
/usr/lib/libx11globalcomm.la and fails to find it.

To get a working KDE session back, hand edit .mcoprc and
.kde/share/config/kcmartsrc.

Searching Bugzilla for X11GlobalComm shows that the missing .la might have been
missing for some time (maybe a forgotten dependency) as there are 3 bugs
reported; I guess that prelinking might be behind this behavior of knotify.
