[IRCServices Coding] Services 5.0 alpha 20 Segfault Bug with /cs info #channel

[Mark Hetherington]

A channel which was suspended tonight on Services 5.0a20 produces the
following in response to /cs info #bots by a user who is not registered with
nickserv:

PANIC! buffer = :testing PRIVMSG ChanServ at services.ctcp.net :info #bots
Services terminating: Segmentation fault

Such a user gets the following text before the segfault:

This has also happened with channels which are not suspended:

PANIC! buffer = :testing PRIVMSG ChanServ at services.ctcp.net :info #trivia
Services terminating: Segmentation fault

in which case the user sees:

The crash appears to happen around where Options and/or Mode lock should be
printed so I assume it is specific options which cause the crash.
