After reading the code I think the patch is good.

OK, but I think that it has to wait; things seem to work now: glade-3 is
a rewrite, let's try to not rewrite the rewrite ;)

At first simple tests I couldn't reproduce them, but today I noticed a
couple of hangs doing for example Save & Close. Not always though...
Archit do you have a case that always hangs?

Anyway I suspect that it's more related to close than to save, as a
matter of fact here is the backtrace of crash that happened opening a
project 1, adding some widgets to it, opening a project 2, adding some
widgets to it and closing project 2 (no saving involved).
