We are currently solving the following issue within our repository. Here is the issue text:
--- BEGIN ISSUE ---
Fix reference to tuplematch in base reporters
The tuplematch object was not referenced in the ReporterBase class when referenced from the GitHubStatusPush class.

It seems this is not an issue when it is executed from the test but only occures when called from GitHubStatusPush. I don't know how I can test this.

Fixes #5765 


## Contributor Checklist:

* [ ] I have updated the unit tests
* [x] I have created a file in the `master/buildbot/newsfragments` directory (and read the `README.txt` in that directory)
* [x] I have updated the appropriate documentation
