Comment 2 for bug 297315

I've updated the description...the smb:// failure still occurs in the Places menu, but I don't see how it can be related since:

The error message is indicating that Gnome doesn't know what application (Nautilus) to use to display the link, but File Browser Launcher correctly launches Nautilus to the incorrect location.
The Places menu lists the items correctly (smb:// links and clarified names), but File Browser Launcher labels the former incorrectly and launches the latter incorrectly (which Places does not).
