A Kick appears has "someone has made no change"

[erdnaxeli]

Describe the bug
Someone kicked someone else. On element android I see (in french) "Someone n'a effectué aucun changement" (which could be translated to "Someone has made no change") while on element web I see "Someone has kicked someone else".

To Reproduce
I am not sure, when I try to reproduce it the event is shown correctly.

Expected behavior
I expect element android to show me "Someone has kickes someone else".

Screenshots

Smartphone (please complete the following information):

• Device: Moto G4 Plus
• OS: Android 8.1.0

Additional context

• App version and store 1.0.4 on Playstore
• Homeserver: cervoi.se

The user doing the kick is a bridged one from IRC, but I don't see why it would change anything.

Can you send the content of the Event please?

[erdnaxeli]

Sure:

{
  "content": {
    "membership": "leave",
    "reason": "attention derrière toi ! "
  },
  "event_id": "$159782383733024WwvKp:iiens.net",
  "origin_server_ts": 1597823837042,
  "sender": "@irc_PrinceCaramel:iiens.net",
  "state_key": "@irc_Tuareg:iiens.net",
  "type": "m.room.member",
  "unsigned": {
    "prev_content": {
      "membership": "leave"
    },
    "prev_sender": "@irc_Tuareg:iiens.net",
    "replaces_state": "$15729348546465XXTuX:iiens.net",
    "age": 335970
  },
  "room_id": "!XOjaoEoAmGOyLzYKMD:iiens.net"
}

The previous event already being a leave might explain it.

The previous event already being a leave might explain it.

Indeed. I have no idea why Element Web is correct though

EDIT: oh, I see, the sender is not the same than the state_key. So I think we can improve our algorithm.

My guess is that the IRC bridge never make the user join, and element android and web have a different behavior with a leave -> leave event. I think I prefer the behavior of element web, but I am sur I don't like the element android one. "Nothing has changer" is really disturbing.

Btw this is not related to this issue but the IRC bridge should probably make a user join before kicking it.
