Package: matrix-synapse
Version: 1.116.0-3+b1
Severity: grave
Justification: renders package unusable
Hi,
with the update of python3-twisted in unstable to 24.10.0-1,
matrix-synapse refuses to start:
$ /usr/bin/python3 -m synapse.app.homeserver
--config-path=/etc/matrix-synapse/homeserver.yaml --config-path=/etc/matrix-

Downgrading python3-twisted to the previous version 24.7.0-3 makes it work
again.
matrix-synapse upstream has modified synapse/http/proxy.py, changing
those lines, however, this just happened last week. So eventually this
should be gone with the next update of matrix-synapse.
