gnome-shell freez when peer whished

[Bartłomiej Szczepaniak <bartus jabster pl>]

Hello,

I'm new to all of this, so forgive me if this is not a proper place for this, nor if i am unclear in my explanation of a problem ...

I spotted this issue while being working on debina/testing inside gnome session with few gvfs mounted smb shares.

I have no session manager, to start gnome-session just invoke "xinit /usr/bin/gnome-session -- :1" form first tty.
To mount smb shares i use program "gigolo" with bookmarks to my local windows shares set to auto-mount.

Base problem for me is that gnome-shell ends black with only mouse pointer visible when remote shares disappears (network shutdown/remote machine shutdown).
I find this in xsession-errors.

To bring back responsiveness to my system i need to kill all apps issuing remote windows shares. After that i ended up with gnome-shell visible but hanging up ever 2-3 sec (for example when dragging a window it moves normally for a second or so then freeze for a 2-3 sec and show up in the current cursor position, moves a bit and hang again).

At this level i got plenty of "glibtop: statvfs 'path/to/my/mout/points/' failed" warnings in tty in which gnome-session was started.
To finally resolve this situation i need to unmount all gvfs windows shares in gigolo. After that gnome-shell is back usable again.

I'm not aware if this is strictly related to gvfs system, or rather to fuse which is used to mount gvfs shares in local file-system.
In my opinion gvfs should automatically unmount vanishing peer and handle applications which has open files inside gvfs mounted systems. Having gnome-shell hangs every time some of local network work station being cutoff is very painful :/
