When I run tarsnappper like this

tarsnapper --target t42-home-etc-\$date --sources /home/a/ /etc/ --deltas 1d 30d 360d - make

I get the following error

 File "/usr/lib/python2.6/site-packages/tarsnapper/expire.py", line 46,
 in expire
     assert len(deltas) >= 2, "At least two deltas are required"
	 TypeError: object of type 'NoneType' has no len()

Not sure what I am doing wrong..
