Comment 5 for bug 385785

If you're running karmic you could try this out from my PPA [1].
Changes;
 - Makes the open location a little bit smarter and does not allow you to open a local path that doesn't exists and shows this by disabling the Open button and adding the text "Location does not exist" under the entry.
 - Opening a remote folder that cannot open now results in that the location dialog gets back to the user with the same path entered from start (as this bug describes)

Comments are welcome, will talk to upstream in the coming days.
