Devise /users/sign_in redirecting to wrong control

Vitals:

ruby 1.9.3p194 (2012-04-20 revision 35410)
[i686-linux] Rails 3.2.7
Devise 2.1.2

The GET /users/sign_in is attempting to redirect to the wrong controller. It has stopped redirecting to wecome#welcome (which works), ans is now redirecting to devise/welcome#welcome, which does not exist and causes a 500 error on the redirect with the following error logged:

ActionController::RoutingError (No route matches {:controller=>"devise/welcome", :action=>"welcome"}):

This started recently, and appears to have been caused by something in a series of gem updates. It used to work perfectly.

Does anybody have any idea why this would start failing ( e.i. which update of which gem) or what I can do about it?

Edits:

Here's the root route from routes.rb:

root :to => "welcome#welcome"

I rolled back to my previous deployment, and the app works again. The deployment was prior to rails 3.2.7.

EDIT: 2012-08-27 -
devise 2.1.2 + rails 3.2.6 + journey 1.0.3 = works.
devise 2.1.2 + rails 3.2.6 + journey 1.0.4 = fails.

devise 2.1.2 + rails 3.2.7 + journey 1.0.4 = fails.
devise 2.1.2 + rails 3.2.8 + journey 1.0.4 = fails.

Rails 3.2.7 & 3.2.8, which are security releases require journey 1.0.4. This leaves me pretty well stuck until I can either get a fix for journey.

回答1:

I had a similar problem with Devise routing to an odd place (in my case "devise/authors").

It was broken after a gem bundle update that included journey 1.0.4. I fixed it by locking journey to 1.0.3.

回答2:

I fixed a similar problem by checking the link_to helpers in the site's header, which is shown also on devise sign-up and sign-in pages. Please see the details here.
