Latest gvfs-update in hardy-proposed causes huge IO-lags

Bug Description

Binary package hint: gvfs

This update:

gvfs (0.2.4-0ubuntu2) hardy-proposed; urgency=low

  * debian/patches/80_samba_browsing_authentification.patch:
     - gnome bugzilla change to allow shares when authentification is required,
       the code try anonymous connections before asking for a password though
       so it doesn't solve the case where anonymous and login are authorized
       but give access to different ressources, see comments on for references
       (lp: #207072)

causes huge problems for me. The gnome-panel takes close to a minute to appear after login, the save file download dialog in Firefox takes ~30 seconds to appear, and there are lags/hangs in general. I had to revert the the previous version of gvfs in hardy-updates, which fixes all these problems.

thank you for your bug report, that's really weird because the update only change the smb code which is not used until you access a the network or do some mounting, could you describe what you do to trigger the issue?

I didn't to anything special to trigger it. But I have my laptop at work, and there's a machine here with the same hostname as my server at home. The server at home has Samba running, but I suspect the one here at work does not, and maybe there's some hang because gvfs tries to contact it, authorize or whatever behind the scenes, but obviously does not get a reply. I'm at work, currently, so cannot spend more time on this now, but can help in debugging later.

you will need to provide extra informations since you seem to be the only one to get the issue so far, are you sure that's a gvfs issue? what gvfs processes are running? does any of those is using ressources?

Of course, I will try to help in figuring this one out.

Here's some info about my setup:
I've got a bookmarked Samba-share in Nautilus like this:

This share requires password-authentication.

The hostname resolves to (the local IP-adress of the Samba-server on my LAN).

The problem occurs because of a difference in behaviour between this new gvfs-release and the previous: now it immediately connects to the share (I've checked with netstat) upon login, even though I don't actively click the bookmark in Nautilus. When gvfs or Nautilus tries to do this at work (when I log in), it hangs, and causes other desktop components to hang as well, such as the panel, file open dialogs, etc. There's no Samba-server with IP at work.

So, should it be trying to connect/authenticate to Samba-shares that are bookmarked in Nautilus but not opened by the user ? This is doomed to cause problems for roaming users with laptops, like myself, that use different servers, depending on location.

If I remove the Samba-share bookmark in Nautilus, it stops trying to connect immediately upon login to Gnome desktop. That would resolve my problem with hangs at work, but it does mean that I can no longer bookmark unavailable SMB-servers in Nautilus without problems. (murphy-md) wrote :

I also get this bug in the latest GVFS update when bookmarking a samba share in Nautilus. The problem occurs whenever I try to open a Nautilus-related program, such as the start menu in the panel, or Nautilus itself. (murphy-md) wrote :

I can also confirm that the fix is to remove the bookmarks from Nautilus.
