I am running Banshee 1.8.0 on a more-or-less vanilla Meerkat installation. I was most pleased when I plugged in an old iPod Nano and it Just Worked.
However, when plugging in the iPod, Nautilus/Gnome asks for an application to handle the newly inserted iPod. The dialog presents no applications that can handle the device and allows no manual choice.
I have reinstalled banshee with
apt-get purge and also
install --reinstall but neither added an association. As before, when manually opened, banshee happily talks to the iPod, it just won't launch on plug.
I suspect there is a missing association in gconf or something similar but I'm not sure where this information lives.
