Aptana Studio 3 Rails 2.x debugging broken?

I'm running Aptana Studio 3 on Windows XP with Ruby 1.8.7, and I cannot get the integrated debugger to work (from app explorer view, running commands->debug server)

I have installed the rubyInstaller DevKit, and the ruby-debug-base, and ruby-debug-ide gems. Here is the error I am seeing whenever I attempt to invoke 'debug server'

Fast Debugger (ruby-debug-ide 0.4.16, ruby-debug-base 0.10.4) listens on 127.0.0.1:4725
Fatal exception in DebugThread loop: The requested service provider could not be loaded or initialized. - socket(2)

This was caused by a bug in Studio 3: http://jira.appcelerator.org/browse/APSTUD-2548

The bug should be fixed in the 3.0.2 release. Also, the link Christopher attached did have details on this issue, including a user's workaround posted near the end of the discussion.

I opened a discussion for this in the Aptana support forum

RadRails 2's rails debugger still works just fine so I switched to that.
