So far I've separately added bug reports that have come from my Plack testing: 15014, 15015, 15016, 15018, 15020. Should I keep filing separate bugs or track them here?
Open 1 bug report / problem, but link them to this bug report.
Lowering severity here - all bugs but one has been fixed and the remaining bug is marked major itself.
Closing as all linked bugs have now been marked as resolved in one way or another.
