Comment 1 for bug 796683

Thank you for reporting this bug. tsclient has been removed from the Ubuntu 11.10 archives. The software has not had a new release in years and was no longer being maintained. Unfortunately that means this bug won't be fixed.

As far as remote folders being visible by default in filechoosers, you're welcome to ask the GTK developers about that. I think there's a good reason for developers having to opt-in to it.
