I encountered this bug yesterday as well.
I spent the entire day rebuilding and attempting to debug, with no luck.

Out of desperation I removed  my install dir and all build dirs.
Basically, I started from scratch.

I left the build to run while I slept.
And this morning things work again.

I'm sure startkde failed at the line
kwrapper4 ksmserver $KDEWM
with the cannot load libkparts.so.4 error


But I did find out that logging in with a failsafe session
and running kwin&;plasma& works pretty well.

Good luck,
Allen
