Comment 7 for bug 190737

This is impacting me quite a bit as well. I don't have as many automount points as robogeek but I see the same issues: my logs are full of trackerd (I suppose) trying to read <mount>/.Trash where <mount> is an automount point configured in auto.master.

You might check this Gnome bug: http://bugzilla.gnome.org/show_bug.cgi?id=511474 it contains a patch (although it's not an attachment so it's not reasonable to apply it). I haven't tried it but it seems to be on-point for this bug.
