From gvfs bug https://bugzilla.gnome.org/show_bug.cgi?id=747718

Sometimes, randomly, mounting fails with "Invalid argument".

During a successful mount:

Can you get a debug level 10 log when it fails ? What kernel version is this being run on ?
Comment 4 Ross Lagerwall 2015-05-14 06:16:38 UTC
See the attached "log for a failed attempt", that is debug level 10.

From the Ubuntu bug report (https://bugs.launchpad.net/ubuntu/+source/samba/+bug/1442972) it is Linux 3.19.0-12-generic.
