No. It's part of a feature. CUPS will automatically run backends that 
are set to 700 as root, and will run all other backends as user "lp"
(or whatever the user is). {So for example if you are using a CUPS 
"pdf:/"-backend as a PDF distiller server for the network, that backend 
should be able to write its results to users' homedirs, it must have 
extended privileges.) The ipp:// backend needs access to the certs
files/dirs. The lpdf:// backend needs access to source ports 721-731,
because RFC "standard" for LPD expects its clients to come from these
ports, otherwise it refuses connections/printing.

chmod-ing {http,ipp} takes away the ability for those backends to
run as root. This may be fine for all FreeNX-related tasks, but may
meet occasions where it disturbs other purposes...
