Comment 2 André Klapper 2013-08-18 09:57:24 UTC

Does that still happen in a recent version? 
1.13 is an old unstable version.

Comment 3 Michal Hruby 2013-08-22 18:47:34 UTC

Yes, it's happening with 1.17 as well, see the top bug at https://errors.ubuntu.com/?package=gvfs-backends&period=month

Comment 4 Sebastien Bacher 2013-11-13 16:34:26 UTC

That's still happening with gvfs 1.18.2

There are similar reports in other distributions, e.g https://bugzilla.redhat.com/show_bug.cgi?id=984217

Comment 5 Sebastien Bacher 2013-11-13 16:36:20 UTC

Report from 1.17.2, https://bugs.launchpad.net/ubuntu/+source/gvfs/+bug/1196193

"While using FTP through Nautilus to modify files on a remote location using Gedit, FTP crashed causing the file being modified to lose all its content - with no backup. That happened to me several times, this time Apport finally recognized an error.

Comment 6 Ross Lagerwall 2013-11-13 17:00:25 UTC

It appears that something is leaking fds. Reassigning to the general component since it's not clear what the culprit is.

Comment 7 Ross Lagerwall 2013-11-14 06:35:57 UTC

If the process runs out of file descriptors, there is a good chance that it crashes at g_cancellable_make_pollfd(). But the reasons for running out of file descriptors vary so there are several bugs here.

The gvfsd-http one is easily reproducible in Ubuntu 13.10 by typing various things in the dash. It repeatedly opens http connections and never closes them, eventually running out of fds and crashing somewhere. The root cause of this is libsoup and is apparently fixed in 2.44.1 (see https://bugzilla.gnome.org/show_bug.cgi?id=695652#c44). I guess Ubuntu should update their libsoup package.

I will close this bug as a dup of #695652 and open separate ones for the bugs linked in comments 4 and 5.

*** This bug has been marked as a duplicate of bug 695652 ***

Comment 8 Sebastien Bacher 2013-11-14 09:31:11 UTC

@Ross: thanks, we got the new libsoup in the current unstable serie:
https://launchpad.net/ubuntu/+source/libsoup2.4/2.44.1-1

let's see if that makes the issue stop as it should!
