Not during upgrade or dist-upgrade operations. This is specifically an
upgrading issue. From man apt-get:
" upgrade:
... under no circumstances are currently installed packages removed,
or packages not already installed retrieved and installed."
"dist-upgrade:
... intelligently handles changing dependencies with new versions of
packages"

my dpkg.log shows that no attempt was made to install libgl1-mesa-dri
automatically.

I'm not sure - other parts of the desktop are working, but I haven't
tested so many things yet. I'm not sure which components depend on MESA.

Actually, empathy's error is from an assert(), a recent discussion on
debian-devel found that assert() is not loved universally loved. There
are various errors from empathy that appear in the same way, and they
should probably all be presented in a popup.

I'll share the results after I try it
