I experienced a similar issue every other time. Here is the NullPointerException of one of the crashes:

It seems like it the plugin doesn't get in some cases a graph object or the inner json object. I wasn't able to debug it that far.

I can reproduce the bug every time when I disconnect a user manually on the Facebook page and afterwards try to re-connect the user from the same mobile session. In this case the session object looks like following:

{Session state:OPENED, token:{AccessToken token:ACCESS_TOKEN_REMOVED permissions:
[public_profile, email, contact_email]}, appId:[APP_ID]}

In the graph user callback the user is null and the response doesn't have a valid content, but an error:

error:{HttpStatus: 400, errorCode: 190, errorType: OAuthException, errorMessage: Error validating access token: Session does not match current stored session. This may be because the user changed the password since the time the session was created or Facebook has changed the session for security reasons.}

I'll have a look on the suggested handling of this error by Facebook and implement a fix. Will keep you updated.

Same issue. It happens every time I remove the app from the authorized applications on my facebook.
