[PC-BSD Support] Automounting problem usb hd w/ UFS filesystem

Hi,

I have a 1TB usb harddisk which I want to use for backups.
For this purpose I replaced the FAT filesystem by UFS2
w/ softupdates and journaling.

When I replug the device, the Mount Tray suddenly terminates
(segmentation fault, terminal output below). Once restarted, MT is
unable to detect the device, although it shows up in dmesg and can be
mounted manually. MT used to work fine with the FAT filesystem.

Did I format the usb drive incorrectly, or is this a bug in MT?


Commands used for ufs replacement (non-root):

$ fdisk -BIv da0
$ bsdlabel -w -B da0s1
$ newfs -L packardbell -U -j /dev/da0s1a


Outputs:

$ uname -a
