Comment 10 for bug 609451

I have another PC that I use Xscreensaver on and on that it works fine with mounted SMB share.

Running Ubuntu 12.04 x64 with gnome3 desktop (fresh install, not upgraded from earlier ubuntu version and so is the other PC I mention in the previous post).
Xscreensaver 5.15, 28-sep-2011 and the screensaver glslideshow.

How I mount the SMB share with fstab:

//nas01/mirrored /mnt/nas01-mirrored cifs credentials=/root/.smb_credentials_nas01,uid=paalfe,gid=paalfe,dir_mode=0775,file_mode=0775,iocharset=utf8,codepage=unicode,unicode 0 0

The different between PC1 and PC2 is:

PC1 = Directory does not exist
PC2 = Works

PC1 = x86
PC2 = x64

PC1 = SMB server is a Netgear Stora
PC2 = SMB server is a Netgear RadyNas Ultra 2
