Instiki devel - Aug 2008 - can''t modify frozen String - 0.13 on Save

I was getting this error when i try to save any page:

"can''t modify frozen String"

(saw the comment about separating text parsing errors from rails errors in
the flash, which seems like a good idea, but I ultimately disabled the
rescue so I could see the full trace)

on 0.13 on a mongrel cluster at MediaTemple''s Grid Server. I poked
around
and traced it to line 385 of /app/controllers/wiki_controller.rb:


382     def remote_ip
383        ip = request.remote_ip
384        logger.info(ip)
385        ip.gsub!(Regexp.union(Resolv::IPv4::Regex, Resolv::IPv6::Regex),
''\0'') || ''bogus address''
386     end

Changing #385 to:

385        ip.dup.gsub!(Regexp.union(Resolv::IPv4::Regex,
Resolv::IPv6::Regex), ''\0'') || ''bogus
address''

seems to work. I''m not super-familiar with this codebase but it seems
this
is a getter method so duplicating the object seemed to be okay to me?
(.clone will preserve the freeze, btw)

A little out of my depth here, but thought I''d mention it if others are
having this problem.

I then got the (unrelated) error "problem "superclass mismatch for
class
Cookie" which I''ve sent another email about.
