Something that I wish more people did when they don't have the time to do a bunch of debugging for an issue they don't experience is dropping a pointer for others. If the response was "I don't have time to work on fixing this. If you wanted to fix this I think it would be in $package and maybe $file. You can create unit tests for this in $place". Or even better "I've added a unit test into master as ignored that is failing right now, if someone can step through and debug this I'd merge it".

It takes a lot of energy but it's a great way to create a community.
