Wait a second. You mean, the callback which is called to report progress 
is also responsible for user interaction? Because, I am handling user 
interaction in the first callback, not in the one updating the 
progressbar-dialog, and it works (I am not yet opening any dialogs 
though, just printing to the standard output).

This would mean, that the sync callback is also called when user 
interaction is required. Besides, I also noticed that it's called way 
more often than just after each transfer, even when no user interaction 
is required.
