I like the idea in principle, but I think it needs to be a bit smarter.
I have a fix pending that will enable the storage browser for install media on
a local connection. We won't want the storage browser squashing the
default_image_path in that case, since there's a good chance that their media
directory and image directory are not the same.
We should have two gconf entries: /paths/last_image_path and
/paths/last_media_path, and give the storage_browser a flag or something to
allow the caller to opt in on which gconf entry we want to store. There's
probably a smarter way to do it but I can't think right now.
A general comment: the gconf entries should change the virt-manager.schema.in.
You can probably just use a default value of "", that way gconf won't throw an
exception the first time you try to access the key.

The hack shouldn't be necessary (see below).

'self.conn' contains the active connection, so you should use that rather than
self.capsdomain...

A couple things here: This will match any path which contains "/dev", you
probably want path.startswith(). Also, this will store the directory of a
chosen storage volume, which isn't what we want. If you make this chunk the
first thing that happens in the function, it should be fine.
