Bug #3863: [BUG] unknown type 0x22 (0xc given)
http://redmine.ruby-lang.org/issues/show/3863

Status: Open, Priority: Normal
ruby -v: 1.9.2-p0

Ubuntu 10.4.  Discovered as part of a move from a working environment of Rails 3.0.0 beta 4 running on ruby 1.8.7 to Rails 3.0.0 running on ruby 1.9.2-p0.

I have taken the following steps, in the order listed:
1. apt-get install ruby1.9.1-full
2. apt-get install libsqlite3-ruby1.9.1
3. apt-get install libdbd-sqlite3-ruby1.9.1
4. vi /etc/gemrc and add line: ":gempath: '/usr/lib/ruby/gems/1.8'"  #(this is so the new gem install finds installed gems)
5. exec bash to have the above take effect in the shell
6. Download and unpack ruby-1.9.2-p0 source. run ./configure, make, make clean and make install
7. vi /usr/bin/rails and change ruby path to /usr/local/bin/ruby
8. confirm on command line that ruby 1.9.2 is working with ruby -v

9. Create a new rails project: rails new new_project
10. cd into new_project and type, 'rails s' to launch the server.
11. Any rails related action, such as point your Web browser to localhost:3000 and clicking on, 'About your application's environment' will produce the crash and accompanying stack trace below.

Rails stack trace below:
