can't mount ntfs partitions in nautilus using ntfs-3g

[Chris <bbshliu@gmail.com>]

Hi,

I use nautilus to mount my usb ntfs hard drive, but I can't write to it.
If I try to create a directory, I get the message: Error creating 
directory: Operation not permitted

In /etc/mtab I find the partition was mounted using ntfs, not ntfs-3g:
/dev/sdb1 /media/disk ntfs rw 0 0

If I manually mount it with the type "ntfs":
mount -t ntfs /dev/sdb1 /media/disk
I also can find the line "/dev/sdb1 /media/disk ntfs rw 0 0".

If I manually mount it with "ntfs-3g", everything works fine.
mount -t ntfs-3g /dev/sdb1 /media/disk
In /etc/mtab I can find:
/dev/sdb1 /media/disk fuseblk rw,allow_other,blksize=4096 0 0

Now, I can conclude that nautilus mounts my usb drive using ntfs.
How can I make nautilus mount usb ntfs devices using ntfs-3g.

ps. I recently do an upgrade, more than 100 packages were upgraded. 
Since then, ntfs-3g doesn't work fine.
