I tried to repro the issue on heroku's cedar stack, but could not.

BTW It's very important to not that this may only happens on newly created cedar.

[stuffmc]

Awesome! When will this make into the gem -- or do you think there's a way to patch this to heroku?

[jipiboily]

Any news about that? Seems like I'm affected by this too....

[indirect]

This was released in 1.1.rc.

[jipiboily]

Doh, my bad! Thanks!
