[cups.general] is CUPS 1.4.4-7 non-deterministic or error prone?

Inspect your different PPDs which cupsFilter entries there are.

I don't know about debian squeeze but at least in openSUSE
some non-CUPS packages install their own *.convs and *.types files
into /etc/cups/ like on one of my machines:
----------------------------------------------------------------------
# for f in /etc/cups/*.convs /etc/cups/*.types ; \
   do echo -n "$f : " ; \
      rpm -qf $f ; \
   done
/etc/cups/pdftoraster.convs : ghostscript-library-9.00-53.1.x86_64
/etc/cups/pstoraster.convs : ghostscript-library-9.00-53.1.x86_64
/etc/cups/pstotiff.convs : hplip-hpijs-3.11.5-32.1.x86_64
/etc/cups/command.types : gutenprint-5.2.7-22.1.x86_64
/etc/cups/pstotiff.types : hplip-hpijs-3.11.5-32.1.x86_64
----------------------------------------------------------------------

Depending on the cupsFilter entries in your PPDs the MIME types and
conversion rules in those non-CUPS *.convs and *.types files are needed.

Therefore it can cause damage when you make /etc/cups/ empty
e.g. to do a clean re-install of CUPS.
