Hi Guix, emacs-telega doesn't work with version 1.5.4 of tdlib (last known good commit: df23842; first known bad commit: 70848cd).
After starting telega (M-x telega RET) the *Telega Root* buffer looks like this: --8<---------------cut here---------------start------------->8--- Status: Ready Fetching chats.. [2:All ] [0:Secrets ] [0:Bots ] [0:Groups ] [2:Private ] [0:Channels ] --------------------------------(all)--------------------------------- {Alice } Last message from Alice 05.01.20 {Bob } Last message from Bob 04.01.20 --8<---------------cut here---------------end--------------->8--- The dot animation after "Fetching chats" keeps looping and the following error message is displayed (2 times, according to the *Messages* buffer) in the minibuffer: --8<---------------cut here---------------start------------->8--- error in process filter: Wrong type argument: stringp, nil --8<---------------cut here---------------end--------------->8--- Deleting the ~/.telega directory and logging in again results in the same error. The state in ~/.telega seems to get corrupted too: Trying to run the known good telega from before the tdlib update afterwards fails because the server seems to crash. Regards, Diego
