I checked in /var/log but forgot about the one in the home directory for
some reason.  That file you mentioned is FULL of stuff like this:

Trust me, I would NEVER torture you with the whole file.  When I say
full, I mean it is HUGE.  I also found this interesting from that file:

I checked some of the dbus packages, most of them only show one package
available for install.  So, I guess if a new one breaks, you are just
screwed.  I thought there was some sort of policy that there was to be
two versions of stuff in the tree so people could go back if needed? 

Well, now what?  Overlay and hope I hit a good version?  Switch to icewm
or something? 

As to your problem, I have not tried suspend yet.  Although, my panel is
all weird right now too.  Sometimes it works and sometimes not.  I do
know this, you click on the K thingy, it locks up for a good little
while.  Don't even think about right clicking and logging out.  It locks
up about everything KDE, including Konsole. 

This sucks.  :/  It sucks more that they removed the previous versions
of some stuff and I can't try going back a version.  Jeeez!!
