=begin
((%rails server%)) crashes reproducable on my system, on a very simple rails v3.1.0rc4 project (attached). The project is only one scaffold plus two validations.

This is on a Debian squeeze system; ruby was installed via rvm.
I'm new to ruby but quite fluent in C/C++ and can use a debugger, if that is needed to track down the bug :)

The crash report:
