hm i didn't know that. this is the problem i think, i will try using a
Glib::Dispatcher instead.
perhaps someone could explain how the Dispatcher works, not in code but
what happens behind the scenes. when i emit the dispatcher in the worker
thread, when does the connected function in the main thread get
executed. will it be called by the signal handling in the gtk main loop?

the only problem is that i cannot pass arguments over a Glib::Dispatcher
neither return values are supported (of course since the dispatcher is
asynchronously). I also need to pass the content of variables from one
thread to the other.
What about a SigCX::ThreadTunnel?

thanks a lot so far
