Comment 15 for bug 1011257

I'm experiencing the same problem on Ubunutu 13.04, util-linux 2.20.1-5.1ubuntu8, gnome-diskutility 3.6.1-1ubuntu1

Here's the relevant fstab lines. (all three were generated by the Disks utility):
----
# Windows is installed on sda1 (and sda3)
/dev/disk/by-partlabel/Win7 /mnt/Win7 auto nosuid,nodev,nofail,x-gvfs-show,x-gvfs-name=windows7 0 0
# these are the 2TB hard drives (usually sdb and sdc)
/dev/disk/by-partlabel/TB_ntfs /mnt/TB_ntfs auto nosuid,nodev,nofail,x-gvfs-show,x-gvfs-name=1TB%20-%20ntfs 0 0
/dev/disk/by-partlabel/TB_ext4 /mnt/TB_ext4 auto nosuid,nodev,nofail,x-gvfs-show,x-gvfs-name=1TB%20-%20ext4 0 0
----
What's interesting is that the ntfs partitions in the above lines mount just fine; the show up in Files browser, etc.
The ext4 partition does not mount, generating the dmesg:
EXT4-fs (sdc1): Unrecognized mount option "x-gvfs-show" or missing value
