[Lucid] Only root can unmount

Hi!

 I've just upgraded my system from karmic to lucid. It's an amazing system, however I'm experiencing a problem, when I trying to unmount ntfs partitions.

The environment: Latest lucid packages:
xxxx:~$ sudo dpkg -l ntfs*
Desired=Unknown/Install/Remove/Purge/Hold
| Status=Not/Inst/Cfg-files/Unpacked/Failed-cfg/Half-inst/trig-aWait/Trig-pend
|/ Err?=(none)/Reinst-required (Status,Err: uppercase=bad)

+++-==============-==============-============================================
ii ntfs-3g 1:2010.3.6-1ubuntu1 read-write NTFS driver for FUSE
ii ntfs-config 1.0.1-3ubuntu5 Enable/disable write support for any NTFS devices
un ntfsdoc <nincs> (nincs leírás)
ii ntfsprogs 2.0.0-1ubuntu4 tools for doing neat things in NTFS partitions from Linux

NTFS-config settings: Every option enabled to every ntfs partition.

And the error message from unmount:
Error unmounting: umount exited with exit code 1: helper failed with:
umount: only root can unmount UUID=42D0D290D0D28A15 from /media/work

The owner and the group for the /media/work is the root, instead of my username and group.

How can I solve this problem without sudo all of the time, when I would like to remove a device with NTFS partition on it?
