User-Agent:       Mozilla/5.0 (Macintosh; U; PPC Mac OS X Mach-O; en-US; rv:1.6) Gecko/20040113
Build Identifier: 

After MozBot joins the channel, any message sent with the format <MozBotName>:
<message> causes the bot to quit (ie "mozbot: help").

The following is the command line output:

Can't use string ("help") as an ARRAY ref while "strict refs" in use at
        /Library/Perl/5.8.1/Net/IRC/Event.pm line 73 (#2)
    (F) Only hard references are allowed by "strict refs".  Symbolic
    references are disallowed.  See perlref.
    
Uncaught exception from user code:

If that's not what you were asking for, please let me know how to find the version.

Wow. Weird. I wonder if 0.75 broke something then.

It would appear so.  I installed version 0.74 and mozbot seems to be running
fine now.  Is this an OS X only bug?

Attachment: patch to get mozbot.pl to work with Net::IRC 0.75

This issue occurs on my PC running Linux as well. They seem to have changed the
interface for the Net::IRC::Event::args function to require array refs. This
patch changes all calls to this function to use arrayrefs

summary should probably be generalized a bit. This seems to be an issue with Net::IRC 0.75 in 
general, rather than just on OS X.

(I just tried to do it myself, but don't appear to have the rights to :-7)
