debfoster does not remove or change keepers file.

[Francisco Borges <frandebo@latt.if.usp.br>]

Hello,

I'm trying to run debfoster for the first time in sarge and it does not
work properly.

I can create a new keepers file with $ debfoster -q but if I start with
an empty list or try to delete a package from within it, nothing changes
in the keepers file and debfoster will not even let me out with 'e'
(remove and exit).

The configuration file has everything at it's default value.

Any hints on what I am missing?
