Confirmed for me as well that these work arounds at least prevent rebooting.
Still it seems something in fuse should recognize a dropped connection and
have a means to deal with it.

could see the Network Manager dialog asking for the network password(*),
with the Nautilus window grayed out above it. I couldn't access the NM
dialog, so there was no way to re-connect and thus unfreeze Nautilus. (The
system wasn't completely frozen, though: the mouse cursor worked, and the
System Monitor applet on the panel updated itself correctly, though nothing
responded to mouse clicks. And I could switch to a text terminal.)
