When I enabled printer sharing [from web interface], cupsd failed to
restart. It wouldn't
print out any error messages or log anything to its own file, but it did
log this to syslog:

tycho cupsd: Unable to read configuration file '/etc/cups/cupsd.conf' -
exiting!

I examined cupsd.conf and found that it contained the following line
containing non-ascii characters:

000000d0  73 20 40 4c 4f 43 41 4c  0a 44 65 66 61 75 6c 74  |s
@LOCAL.Default|
000000e0  41 75 74 68 54 79 70 65  20 90 ec 05 08 63 0a 3c  |AuthType
.....c.<|
000000f0  4c 6f 63 61 74 69 6f 6e  20 2f 3e 0a 20 20 41 6c  |Location />.

Removing the DefaultAuthType line brought the server back to life.
