If the kded hang bug is not reported yet please do so! We can't fix bugs we don't experience and are not reported...
Next time it happens -- and it happens a lot -- I'll get a backtrace and report it. (Killing kded brings it back to life, working -- unlike in KDE3, where it caused kdeinit to segfault. So an improvement there.)
Now trying to get kdeaccessibility to build. At all... :/
