Bug #1777: <main>:330: [BUG] Segmentation fault

This sounds more a MySQL/Ruby binding error than Ruby itself.

Also, please provide a minimal test case, not the output of your Rails application.

From my experience, this sounds like a mismatch between MySQL and the Ruby binding. Can you tell us which version of MySQL are you using?

I get this error too.  Minimal test case Ruby program is this one line:
   require 'mysql'

10:58:03 > mysql --version
mysql  Ver 14.14 Distrib 5.1.32, for Win32 (ia32)

10:58:30 > ruby --version
ruby 1.9.1p0 (2009-01-30 revision 21907) [i386-mswin32]

10:58:49 > gem list
*** LOCAL GEMS ***
[snip]
mysql (2.7.3)

First: binary mysql gem 2.7.3 will not work with 1.9.1, you need 2.8.1

Second: binary mysql gem links against 5.0.xx version of MySQL, and
there is a API incompatibility with 5.1.xx.

I've commented about this over ruby-talk and also on this post:
