Actually, according to the apt logs, libgtk-3-bin was installed before
libgtk2.0-bin.

More precisely, here is the sequence of events:

- 2012-09-27: libgtk-3-bin 3.4.2-4 installed (upgraded from 3.4.2-3);
dpkg-divert works fine (but no file actually diverted, since
libgtk2.0-bin not yet installed)
- 2012-11-24: libgtk2.0-bin installed (not installed previously); this
install was part of a large install of packages of foreign arch i386
- 2013-01-10: failed upgrade of libgtk-3-bin to 3.4.2-5

I tried to reproduce these steps on my system and got no crash. I am
therefore tagging as unreproducible for now.
