"undefined method `accept'' for nil:NilClass" error after upgrading to 3.2
I''m getting the error undefined method `accept'' for nil:NilClass in my controller. This is on the development environment running on OSX with mysql. Below is the full stack trace and also my bundle/gem setup information. This is reported by a couple of others on the ruby forums, and I''m trying to see who else might be running into this and if there is a known solution.

Show us what''s there. Chances are you''ve got a call that looks like "someobject.accept(someargs)". The variable someobject is nil. Trace down where that variable should have gotten set, and see what you can figure out about why that didn''t happen, or why the variable it got its value FROM was nil, or why it got RE-set, to nil, afterward. -Dave -- Dave Aronson, Available Cleared Ruby on Rails Freelancer (NoVa/DC/Remote); details @ http://www.DaveAronson.com/. -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

Hi all
I''ve taking over the managing of a Rails system (v. 1.2.3) that has
been writing to production.log for several years now, and the log had grown to
16 Gb, taking up half the server disc space.
I removed the logfile, doing:
$sudo mv production.log production.log.old
$sudo touch production.log
$sudo chmod 666 production.log
$sudo rm production.log.old
Everything works fine except my new log file does not get written to. Is there
any way to restart logging without restarting Rails? The server is running
several Ruby components as well, defined in /lib, and they also write to the
production log.
Will I need to restart the Ruby components - or is it sufficient to kill the
Rails processes and restart them?
I''ve enclosed a section of ps aux output
