I’ve looked again at the strace log and can’t find anything obvious such
as a config file in /home or /etc that would tell it to load
libcanberra-module.

However, I built Evince locally with glib-or-gtk-build-system, and it
doesn’t mention anything about libcanberra:

So I’m pretty clueless.  Could it be that it receives some message over
D-Bus (on your machine) telling it to load the thing?  What does
‘dbus-monitor’ show?

Sure, but that would be cheating.  :-)

Thanks,
