Description
This issue has been migrated from [#1995](https://github.com/matrix-org/synapse/issues/1995).
---
Prerequisite: have Riot and Quaternion running at the same time (other clients might work, too).
1. Start a new chat with someone in Riot.
2. Find two identical (with the same id) `m.room.create` events within the same timeline batch coming in the next /sync (actually, this crashes the most recent Quaternion; I changed now an assertion for no-dups-in-the-batch to a no-op with a warning).
