Very odd errors from bind 9.2.2

[Josh Brooks]

Suddenly, with _no change in configuration_, I am seeing these three
errors in /var/log/messages every time I HUP my named process:

Oct 24 22:56:38 ns1 named[8255]: dns_master_load: /etc/namedb/s/.:1:
unexpected end of line
Oct 24 22:56:38 ns1 named[8255]: dns_master_load: /etc/namedb/s/.:1:
unexpected end of input
Oct 24 22:56:38 ns1 named[8255]: zone ./IN: loading master file
/etc/namedb/s/.: unexpected end of input

This confuses me greatly, as the file it seems to be telling me there is a
problem with is:

/etc/namedb/s/.

which is essentially:

/etc/namedb/s/

Any thoughts ?

thank!
