I got this crash by adding the obsolete (removed from 1.6.x on)

BrowsePoll <host>

to /etc/cups/cupsd.conf. The crash disappeared after removing the entry.

Everyone who suffers this bug, please check your cupsd.conf for obsolete or mistyped entries and remove them (or at least comment them out). Obsolete from 1.6.x are as far as I know: BrowsePoll, BrowseAllow, BrowseDeny, BrowseOrder, and BrowseRemoteProtocols. Also the argument "cups" for BrowseLocalProtocols is obsolete, but I do not know whether the valid keyword with the invalid argument also causes the crash.

See also bug 1052897.

The attached cupsd.conf of the original poster has following offending lines:

BrowseOrder allow,deny
BrowseAllow all
BrowseRemoteProtocols CUPS dnssd

Please remove these lines and try to restart CUPS. Does it work now?
