Your problem is that you are making calls to GTK+ from two different threads 
and you are not using the GDK lock (your call to hellothread::thread_dilate() 
is executing in a second thread and making calls to the button object).  If 
you happen to be using Windows you also have the problem that the GDK lock 
will not help even if you were using it.

The better choice is to only call GTK+ functions in the main GUI thread and 
use Glib::Dispatcher to communicate with that thread.
