Bug#609201: gvfs: Gnome automounter error while mounting usb ntfs disks

[Christian Schwamborn]

Package: gvfs
Version: 1.6.4-3
Severity: normal

when I try to connect a ntfs formated disk, I'm getting this message:

Error mounting: mount exited with exit code 1: helper failed with:
Error opening ' /dev/sdb1': Permission denied
Failed to mount '/dev/sdb1': Permission denied
Please check '/dev/sdb1' and the ntfs-3g binary permissions,
and the mounting user ID. More explanation is provided at
http://ntfs-3g.org/support.html#unprivileged

mounting other formats (i.e. fat, ext) works just fine

I checked that I'm in the right groups (at least it looks right)
cs at pikass:~$ groups
cs cdrom floppy tape sudo audio dip video plugdev staff users netdev bluetooth
lpadmin fuse scanner

permissions for /dev/sdb1 seems to be correct
cs at pikass:~$ ls -l /dev/sdb*
brw-rw---- 1 root floppy 8, 16  7. Jan 11:03 /dev/sdb
brw-rw---- 1 root floppy 8, 17  7. Jan 11:03 /dev/sdb1

I even tried to set a uid bit (4755) on ntfs-3g, as suggested by http://ntfs-
3g.org/support.html
then I'm at least able to mount the device via shell as a normal user, but it
doesn't solve the problem in gnome (and it's na ugly hack)

It seems to apply only for amd64, since I performed two squeeze installations
in the last weeks.
The first was around the 16th of december 2010 on an i386er machine as a test
and two days ago another one as amd64. Automounting ntfs drives in Gnome on the
i386 installation works just fine but not on the amd64 machine.

cheers, Christian
