Comment 5 for bug 1547811

Hi flohack, yes it is the duplicate of that one. But I appreciate the back trace!
I suspect it's a secret API layer 20 call that's crashing it, related to state of a secret chat.
I'm not sure when we get that fixed, though it has been escalated to critical.
I hate to suggest this, but if you need a workaround, and you do *NOT* care about loosing secret chats:
rm -rf .config/com.ubuntu.telegram
Otherwise, I'm bit clueless what I can recomment. We'll just have to get this fixed.
