You installed telethon==1.5 and the library only works with telethon~=1.4.3, but I believe we need to push the change to PyPi.

Even when changing to telethon 1.4.3 I still get an error

Looks like the filename sanitisation bug. By the way, the Telethon version specifier is now on PyPI, so that shouldn't happen again.
