Somewhere you are trying to serialize a Proc object (looks like you’re
trying to put one in the session).

Interesting! I’ve found the problem, but not the fix. I was store my
ActiveRecord errors in the flash as shown below:

flash.now[:errors]= @object.errors

This apparently causes problems when you are using PaperClip and there
is a
validation issue. It may be trying to put the file in the ActiveRecord
Errors object.

I’m just going to have to change how I do my flash error messages…

Thanks!
Tom
