Unable to access location Failed to mount Windows share: Invalid argument

[penalvch]

When attempting to mount a Ubuntu samba share via Nautilus, it notes:
Unable to access location
Failed to mount Windows share: Invalid argument

However, mounting via smbclient works fine. Hence, this would be an issue with Nautilus/backend.

As per https://bugzilla.gnome.org/show_bug.cgi?id=747718#c13 this is a samba library bug.

yes this bug affects me also - ubuntu 14.04, i also tried command line with cifs, following are some of errors:

CIFS VFS: Malformed UNC in devname.
CIFS VFS: cifs_mount failed w/return code = -6

This no longer affects me as I don't use Trusty, Utopic, or Vivid, and this is not reproducible with Wily+Wily.

I am now having this error on mounts that worked before on Ubuntu 18.10.
