So if I'm clear about this, you have a stable AMD64 system with ~AMD64 KDE?

If you upgraded from KDE 4.3 did you try deleting all the old KDE
configuration stuff and starting new? I've not had your problems with
nepomuk but I run either AMD64 with just a couple of ~AMD64 packages,
or full ~AMD64. I haven't seen this problem on either system. However
I do run ~AMD64 portage, sandbox, gentoolkit, eix and a few other
installation things on all my systems so possibly that's part of it.

Good luck,
Mark
