[Kde-bindings] Constructor error with QtRuby redux

[Caleb Tennis]

It seems that last month's issues with Debian are creeping over to Gentoo.

Namely, any Ruby version >1.8.3 (that is, 1.8.4_pre{1,2}) exhibit the same
issue, where no initializer code is run after a "super" call.

I put in a few debugging "puts"es, but I'm not set up to fully debug the
cpp source at the moment.  however, I'm never seeing
Internal.try_initialize get called, which is a bit bothersome.  I'll
continue investigating in the morning unless someone else gets to it.
