Sorry for replying to myself, but after installing fso on my laptop and starting my application there the signal connection DOES work. So I guess it's related with Qt on my Freerunner...

I tested it with GPS Dummy device and received the FixStatusChanged signal. Also dbusviewer showed objects paths and signals/methods there.

I built Qt4 for SHR-unstable with SHR Makefile, Qt 4.5.2.

Does anyone have a Qt version running on SHR where connection signals DOES work?

Thanks,
 Christian
