My apologies, I'm really behind with sorting out bugs in QtRuby/Korundum. I've 
been really busy with a stressful day job, and also working on the QtScript 
smoke binding, and just hadn't had any time for Ruby. There are quite a few 
things I want to improve in QtRuby after working on the QtScript binding, as 
well as fix these outstanding bugs for the KDE 4.4 release.

No problem at all, thanks for taking the time to report the bugs. I'll try and 
investigate the problems as soon as I can.
