dpkg triggers aren't a problem if the files being executed are
in /usr/bin - i.e. not in Multi-Arch paths or Multi-Arch: same
packages. Put the executables into a Multi-Arch: foreign package and
the triggers will work just fine.

What's the reason for not putting these executables in /usr/bin where
only one architecture would exist on the filesystem?

Triggers, in general, are fine in Multi-Arch world, I've had no
trigger related problems, except this one. What matters is that the
processes being triggered here are in /usr/lib/ instead of /usr/bin.
Executing anything in /usr/lib/ in Multi-Arch world is just going to go
wrong.

What is gio-querymodules meant to do as i386 on amd64? Is it going to
redo the work of the amd64 version? AFAICT these triggers should not be
run once-per-foreign-architecture but once per upgrade.
