That's why I wrote the "not recommended" note.

This is not really expected. I can try to have a look again later
in the week. In any case, if you are interested in having support
for anything except the latest 4.x and 5.x releases, I need some
help. It's usually just one file that needs to be touched
(share/qtcreator/dumper/dumper.cpp), but I can't realistically 
reproduce all interesting configurartions myself.

"10.6" might indeed be related to the problem, I don't think this
has been actively touched for quite a while.

I would be surprised if you get QObject properties etc, but your mileage
seems to vary ;-)
