This has been going unfixed for years now.

For me, the fix involved adding the following into /etc/apparmor.d/usr.bin.vidalia.

/usr/share/glib-2.0/schemas/ r,
/usr/share/glib-2.0/schemas/** r,

Then, I reloaded AppArmor /etc/init.d/apparmor reload and the contraption worked. If you get asked about your Tor control password, restart tor /etc/init.d/tor restart.
