[kde] kcminit problem.

I've been having a kcminit problem for a a few days, since I upgrade my X11 to
to 7.0. For the record, it's a Gentoo system. I've solved the problem, but
wish to share the solution for any others that run into this.

After logging in (via KDM), I'd get a SIGSEGV from kcminit. The backtrace was
not useful. Once I closed the dialog from kcrash, KDE came up and seem to be
OK. I noticed one odd behavior, which was I was getting audible bells in
certain circumstances even with the KMixer Mute turned on, and headphones
plugged in.

The problem in my case turned out to be with kgamma. I didn't have it, but
kcm seemed to think I did. Rebuilding kdegraphics corrected the problem.
But the useful part of this message is how I figured this out.

At first, I ketp logging out and back in to see if I could figure out more.
It turns out, if you run kcminit from a command line (konsole), it gives some
information. Even better, you can run "kcminit --list" to see which services
KDE is trying to initialize. And then you can run kcminit <module> to where
<module> comes from the --list output. This attempts to initialize just
that one service. Trying this for all the services, I figured out that
kgamma was the only problem.

Since kgamma wasn't on the system, I did an "equery belongs kgamma" to find
out which ebuild would provide it, and then re-emerged that package. Poof.
Better.
