The problem seems to be coming from a mix of GTK 2 and GTK 3 headers.
Looking at the build logs of the current version, I see that the call to gcc already has "-I/usr/include/gtk-2.0" (coming from libgtkdatabox itself) and -I/usr/include/gtk-3.0" (coming via the pkg-config file of glade).
As libgtkdatabox is GTK2 and glade GTK3 there are data structure that are different (has this even worked in the past?)
I'll push a NMU to the delayed/10 queue with some other changes. Kind regards, Laurent Bigonville
