I changed to -march=k8 in the make.conf file, removed all packages from
kde-base to trigger a meta recompile, then re-installed kde-meta and
compiled everything else using emerge -Dav system and emerge -Dav world.
I still get the same error.

from dmesg
kded4[16907] trap invalid opcode ip:7fde193e74d7 sp:7fffa5120510 error:0

error:0 in libqtGui.so.4.7.4[7fde19226000+a74000]

So it appears that the problem is in libQtGui.so.4.7.4
How do I know that I've recompiled this?  I suspect this is still a
hangover from the original compile settings.
