Not yet. I will fix the wording. It should read asserts. 

See below the backtrace. I hope to create a bugreport but i can't guarantee 
it. I'm not that keen on reporting bugs i am not sure are bugs given the 
success i had with reporting things i consider bugs.

Specifiying no interface but wanting to emit signals is quite some wrong usage 
if i understand dbus correctly. Which i'm not sure.

But i'm pretty sure qt could do a much nicer job of telling me what is wrong. 
Took me quite some time to figure out what the problem is.
