Bug#584731: evince hangs when a recent opened file is on a stalled partition

[Pierre Habouzit]

Package: evince
Version: 2.30.1-3
Severity: important

To repeat that:
  - have a samba mount somewhere, open a PDF document that resides on
    it, scroll in it a bit, and exit.

  - make then sure that you cannot route any packets to this samba mount
    without unmounting it (for example, add a broken route specific to
    the samba mount in question so that everything timeouts).

  - open another PDF document _NOT_ on the samba, anywhere local works.


Result:

  - evince hangs in the background, sometimes for a very long time.


Expected result:

  - evince starts instantaneously.


I don't know what evince does with its "recently opened files" list, but
it should not be done in a synchronous way. I suppose that the same
would happen for a broken NFS mount or any kind of broken mount.

FWIW my use case is that I have a few mounts that route through a VPN,
and sometimes the VPN is down (mainly because when I put the laptop to
sleep, this dumbass NetworkManager isn't restarting the VPN
automatically like it should and claims it does). The real problem here,
is that I've seen evince hang like that for 6-8 months now, and it's
only now that I've been able to connect the hangs with the stalled
mounts. That's not really the kind of things that look correlated at
first :)
