That screenshot is not helpful at all. Anyway looks like your phone is heavily modified, and maybe some program you have is causing the problem. Anyway try deleting the just file /home/user/.yappari/chats.db only and then running Yappari. I'm not sure it's gonna work but at least you can try. If it doesn't help then I can't help you. You'd have to debug the software yourself, the sources are available.
