Title: Konqueror crashed when having a Kate-KPart embedded in a page and using the search bar on it I clicked outside the part, in the web page itself

What I was doing when the application crashed:
Qt: 4.5.1 (qt-copy  958974)
kdelibs svn rev. 960693 / kdebase svn rev. 960693
on ArchLinux i686 - Kernel 2.6.29.1

I was trying to reproduce bug https://bugs.kde.org/show_bug.cgi?id=191517.
So I loaded the "www.Linux-usb.org" page on Konqueror and then I clicked in the "ID List" link. It prompted to open a text/plain file and I Opened it.
The main frame loaded the Kate kpart showing that file
(Focus was on the main page, not in the KatePart), I used "Search in this frame" but the searchbar didn't found anything inside the file. (I guess that is bug 191517).
Then I clicked inside the KatePart, and I noticed a longer Edit menu (of course, as it now has the KatePart Edit menu items), I clicked Find..., the searchbar now appeared inside the KatePart and I could do some searches.
Later I clicked outside the KatePart (the left frame) and Konqueror crashed.
