The same bug just happen to me with an android client. Not sure which one. I assumed it was an iOS thing because my secret chats were never delivered to the iOS user, although the user got notifications. And i was planning on filing a separate bug for that. It seems i can't leave any secret chat without producing this error. Secret chats have only the 'leave' option, btw, no 'clear history' perhaps that is expected?
