Firefox Crashes when Opening Downloads, or Inkscape Cannot Open its own Files (pick one)

On my Debian Sid machine (2011 Oct), I am running Firefox 6 and I'm unable to open my Downloads window. There is a work-around per this bug report:

As root, edit the file at /etc/gnome-vfs-2.0/modules/default-modules.conf and comment-out (put a # sign in front of) the file: file line, so that it looks like this:

#file: file

Save that file, restart Firefox, and you're good to go!

This does seem to prevent Inkscape from being able to open its own files, however.
