I get the option to set up a Telegram account in KAccounts kcm, but then this error message: This IM Account cannot be created - a Telepathy Connection Manager named 'morse' is missing or it cannot handle protocol 'telegram'. Please try installing morse with your package manaager. It doesn't seem to be installed nevertheless. https://akulichalexandr.wordpress.com/2016/09/16/telegram-connection-manager-morse-released/ Reproducible: Always
