Replying to myself. The described behaviour can be triggered in both, 
wheezy and sid by installing libgtk-3-0 and libgtk-3-common 3.2.3-1 from 
snapshot.debian.org [1].
The same behaviour can be seen with 3.2.1-1.
With 3.3.16-1 gThumb starts fine (but throws a ton of warnings on 
stderr).
With 3.4.0-1 everything is as fine as with 3.4.2-2.

My current guess is that libgtk-3-dev should not generate >= 3.2 deps 
but >= 3.4 ones -- gtk+3 maintainers, what do you think?

Evgeni
