Using SSHFS to mount remote file systems in the user space, I have the problem that all instances of Nautilus use to freeze, if one of the mounted hosts is unreachable. That problem occurs with Nautilus 2.X and 3.X and I cant find any solution until today. This problem makes SSHFS almost unusable, at least using an unstable WLAN or something like it. Is this a Nautilus bug? Can anyone confirm this problem, is there a solution?
This is Bug 657208 in GNOME Bugzilla.
Also there is a possible workaround found in SSHFS FAQ:
