This is on 4.4.0 (and 4.4.1-prerelease). I don't have 4.3.5, and I 
unfortunately have any more time today to downgrade to test.

This sounds like a bug for Trolltech. Seriously. My head starts swimming every 
time you start looking at the implementation for the meta object stuff in Qt. 
So please file a bug with them. Possibly also mention it on the kde-devel 
list, because a lot of Trolls hang out there as well. Maybe someone else has 
seen it.
