Crash when trying to rsync to external NTFS-formatted HD

[Leslie Jensen]

Hello list.

I'm trying the following on my 9.1-RELEASE #0 system:

Mounting the external HD
ntfs-3g /dev/da0s1 /mnt/backup/

And doing
rsync -av /home/les /mnt/backup/BSD_backup/


I get "Building incremental file list" for about one minute then my 
system freezes and reboots.

I'm aware that NTFS might be the culprit. I have chosen it for 
convenience and the possibility to move my data to machines without FreeBSD.

Manually copying of files one by one works.

Thanks
