rake test passes, but rake test:major_supported_rails --trace gives me:

Not sure what to do with that.

I definitely lost some time trying to figure this one out the other day. In the end, I just used a string rather than a symbol. Thanks for this.

For others who might find their way here I'll repeat my comment from issue #592:

The workaround (which doesn't require this patch) is to change:

config.logout_link_path = :logout_path

to:

config.logout_link_path = :logout_url

or:

config.logout_link_path = 'logout'

Hi George!

Thanks for this patch! I'll take a look into why the rake task isn't working for you. It all passed on my machine.

Merged into master 7dd809e
