KDE stopped working after -current upgrade

[Mikhail Teterin]

I had KDE running nicely since November on my dual PII. After rebuilding
-current on Saturday, I can not login -- seems like the window manager
is crashing:

	pid 52040 (kdeinit), uid 105: exited on signal 6 (core dumped)

The only unusual thing is -- PTHREAD_LIBS is set to -lthr... I tried
rebuilding Qt, kdelibs, and kdebase -- still the same.

Any ideas? Thanks!
