[Launchpad Bug Tracker <1280867@xxxxxxxxxxxxxxxxxx>]

You have been subscribed to a public bug:

[ Description ]

If a samba share has an empty name, nautilus will crash when you browse
to the listing of shares.

[ QA ]

- Be on a setup (or create one) where you tickle https://bugzilla.samba.org/show_bug.cgi?id=10896
- Open nautilus, hit ctrl-l, browse to smb://workgroups
- Nautilus crashes (or doesn't crash with the fix)

[ Fix ]

Fix nautilus_file_peek_display_name () to not return NULL ever, as some of its
callers weren't prepared to handle this.

[ Regression potential ]

Should only change crashes to non-crashes, but maybe a caller I missed
handled NULL properly and now will behave weirdly. I grepped the source
and didn't find one, though.

[ Original release ]
