Due to https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=963035 , right now
we're in a state where chromium has

    Conflicts: libavcodec58 (= 7:4.3-1), libavcodec58 (= 7:4.3-2)

however, 7:4.3-2 is the only available version of libavcodec58.  I assume this
is why aptitude bails out here.  There isn't a fix, so it's understandable
that it can't come up with one, but "fatal exception" isn't usually the way I
expect that to be presented :)

Thanks,
--Robbie
