It's very possible that the internal documentation at
/usr/share/doc/dpkg-dev/triggers.txt.gz is not very clear on this
subject, and I'd be happy to clarify it!

Hmm, and thanks for the retest!

So, I didn't try to reproduce the error first, and went directly for
a hunch. I followed your recipe, but in steps 3* and 6* I also amended
hicolor-icon-theme. And that seemed to fix the upgrade. Take into
account I've not had the time to analyze the dependency chain, nor if
my initial setup (not using cowbuilder, etc) matches, so maybe this is
an error in procedure. If someone else can reproduce, that'd be helpful,
otherwise I might retry tomorrow.
If this does fix it, it might be helpful also to try just amending the
triggers in the stretch "mock", instead of in the jessie one, to see if
such a fixed package would be enough.
Thanks,
Guillem
