Cannot manage team email addresses (BB-7640)

In email settings menu (bitbucket.org/account/user/[username]/email/), existing email addresses don't appear, there is only the label "Loading..." that isn't replaced.
When I try to add a new address, then appears a label "Resource not found".

This happens only for the settings of the team named 0xdeadc0de, in my personal account and in an other team I administer the email settings work fine.
