Something about SVN r320844 causes almost all KDE applications to fail 
on a signal 6.

I've recompiled KDE and other components obviously dependent on kernel 
structures (e.g. everything dbus-related). I still get core-files with a 
back-trace that looks like:

SVN r320843 works, r320844 doesn't :-(
