With help on #debian-gnome IRC we managed to fix both problems (they
are independent).

The original bug was because /usr/share/pixmaps/chromium.png is a
directory, which caused an exception to be thrown, and pavucontrol did
not catch it.

The second problem was already fixed upstream, so I am backporting that too.

I will upload a fix shortly.
