It does. I wish more people recognized that bug reports are contributions.
Probably only 1% of users file bug reports. That means for every 100 times a bug is found by a user, 99 of them won't bother reporting it. Devs can't fix a bug they dont know about...
I think it depends on the project. Some maintainers really only want extremely comprehensive bug reports that realistically only another dev could produce. All kinds of logs, sometimes requiring special packages installed to produce them.
Which makes sense because someone just saying "it crashes sometimes" doesnt provide much to go on.
