Rails 3.0.0 can crash Ruby 1.9.2p0 (23 oct 10)

A picture of Ruby (really - she's a belly dancer named 'Ruby'
who is currently being linked to the Italian prime minister)

I converted a Rails app to Rails 3, and upgraded Ruby to 1.9.2p0 as recommended. I clicked on a link, and the Ruby interpreter crashed. Exactly what happened is difficult to determine, but I enclose some of the crash trace, and I solved it by reinstalling Ruby 1.8.7-p302 from

http://www.ruby-lang.org/en/news/2010/08/16/ruby-1-8-7-p302-is-released/

then 'sudo apt-get install rubygems' then 'sudo gem install bundler' then 'bundle'
