If a report is vague (e.g. just a generic error message) and has no reproduction, it will receive a "need reproduction" label. If no reproduction is provided within a reasonable time-frame, the issue will be closed.

Reproductions must be [short, self-contained and correct](http://sscce.org/) and must not contain files or code that aren't relevant to the issue — please do NOT just paste a link to your project. Explaining how to reproduce is generally not enough. It pushes the burden of creating a reproduction project onto a small set of volunteer maintainers and isn't scalable. If no reproduction is provided, the issue will be closed.
