  I have a long shot -- I've had a bit of trouble with the nepomuk
services on KDE4, although not NVidia-related (as far as I know),
and not on experimental, as I generally stick with "squeeze".

  Anyways, your traceback has nepomuk stuff in it, so as a first
cut, I suggest disabling all that stuff.  In the KDE gui, you can
do this via "System Settings" -> "Advanced" -> "Service Manager",
and disable the "Nepomuk Search Module".

  This may fail if the "System Settings" is one of the KDE apps
that blows up, of course.  In that case, maybe you can do 
something more blunt-instrument-like, like renaming the 
nepomuk executable or something.

  Otherwise, there's the usual "is it plugged in" stuff:

  I've sometimes had issues when Debian-packaged OpenGL updates
clobber the NVidia-provided OpenGL library files, but have
always been able to clear them by re-running the NVidia 
installer.  Kernel updates can do this too, not sure why.
(Your symtpoms don't really match this profile, but it's easy 
to try...)

  Also, the K desktop is vast and contains multitudes.  If it's
convenient, maybe create a fresh, blank account on the problem
system, log into it in KDE, and let the config wizards do their
thing, and see if the problem still manifests -- if it doesn't,
then you've isolated the problem to one account's desktop 
settings.  It's possible the 4.4 to 4.6 migration isn't as
clean as it could be, and something's getting confused.
