 Looks like it's tripping on the authentication challenge from the server:

 {{{
 WWW-Authenticate: Digest
 realm="asterisk",nonce="[redacted]/[redacted]",opaque="3cb78cf26cb36db9",algorithm=md5,qop="auth"
 }}}

 Notice at the end of that header, the ,qop="auth" that pidgin is
 complaining about in the above debug log.
