Mail notification incorrectly sent for events not enabled in application types

This is a bug happening to me on xwiki.org today: I received an email about 5 different changes, all being page editions. The problem is that:

• 1. I have email notifications disabled for all page changes (I only receive alert notifications for those);
• 2. I don't have any custom notification filter for the pages for which I received an email;
• 3. I do have mail notif enabled for mentions, but the diff shows that there wasn't any related mention to me in those editions;
• 4. it's the first time that I receive an email for page editions on xwiki.org and I haven't changed recently my notification settings
