Bug Description

I tried to browse a Windows Share and after input of my credentials Caja fallbacks to computer:/// instead of showing the contents of the Windows Share, after looking in /etc/syslog I've found:

Apr 13 13:02:56 quasar-workstation org.gtk.vfs.Daemon[1539]: ### SMB: do_mount - [smb://bbvdfs.bf/dfs; 1] res = 0, cancelled = 0, errno = [0] 'Conseguido'

Steps to reproduce:

1. Launch Caja
2. Navigate to a Windows non public Share

Based on the segfault being in liblibsmb, I'm reassigning this to samba. Further investigation required to sort out what's actually going on.
