[futex]

I got this error when i start errbot 6.1.9

10:49:26 INFO errbot.bootstrap Found Storage plugin: Shelf. 10:49:26 INFO errbot.bootstrap Found Backend plugin: Telegram 10:49:26 DEBUG errbot.storage Opening storage 'repomgr' 10:49:26 DEBUG errbot.storage.shelf Open shelf storage /bot/errbot-ve/data/repomgr.db 10:49:26 ERROR errbot.bootstrap Unable to load or configure the backend.

In the file errbot/backends/telegram_messenger.py it seem a declaration is missing
I have replace the line

from typing import Any, Optional, Union
by
from typing import Any, Optional, Union, BinaryIO, List, Optional

And now it's worked
