If a XEP-0147 message action is attached, Gajim determines the JID incorrectly. This splits possible message actions from the action itself.
I don't know how to process the keys properly (in an attempt to fix #9108).
Step 1. Fetch and check out the branch for this merge request
git fetch https://dev.gajim.org/wurstsalat/gajim.git uri-message-keys git checkout -b wurstsalat/gajim-uri-message-keys FETCH_HEAD
Step 2. Review the changes locally
Step 3. Merge the branch and fix any conflicts that come up
git fetch origin git checkout origin/master git merge --no-ff wurstsalat/gajim-uri-message-keys
Step 4. Push the result of the merge to GitLab
git push origin master
Note that pushing to GitLab requires write access to this repository.
Tip: You can also checkout merge requests locally by following these guidelines.
