Comment 1 for bug 1377062

A clarification on the impact of this bug: if an application is granted access to an account via the in-app flow (that is, if the user doesn't manually go to the system settings to enable the app), then everything works fine as expected.

The bug is affecting the usability of the applications only if the user enables an application from the system settings, and the application has never been enabled before (by "enabled" here I mean "granted access to a specific account").

If you are hit by this bug, then you need to go visit the account in the System Settings, disable the affected application from there, then restart the application. If the application has the right code to talk to OA (unfortunately, at the moment the facebook and twitter webapp don't), then the user will be prompted to authorize the application, and things should work.
