For cross-wiki uploads it must be avoided to add language templates without an effective content (example: https://commons.wikimedia.org/wiki/File:Afafa1-1.png).
Note: From my perspective non-effective content exclusively contains whitespaces and newlines in any combination. But maybe these two are not correct.
| Subject | Repo | Branch | Lines +/- | |
|---|---|---|---|---|
| mw.Upload.BookletLayout: Require non-whitespace description | mediawiki/core | master | +2 -2 |
Hmm, yeah. We require that this field not be empty, but we aren't counting whitespace-only content as empty. It doesn't seem like people are exploiting this often, though (or the uploads quickly get fixed/deleted), since the category for this error is almost empty.
Of course it is not a big issue, but it will create a constant stream of work for cleaners which could be avoided by a minor extension. Btw, this issue prevents such a file appearing in the right category which is "Media lacking a description".
Change 260401 had a related patch set uploaded (by Bartosz Dziewoński):
mw.Upload.BookletLayout: Require non-whitespace description
Change 260401 merged by jenkins-bot:

Why does that still happen? E. g. https://commons.wikimedia.org/w/index.php?title=File:SI_badges_-_progressive_scheme.jpg&action=edit
That image was uploaded using a different tool, the "Cross-wiki upload" tag is not there and the file page reads "Transferred from en.wikipedia to Commons using For the Common Good." Please report the bug to its creator :) Cross-wiki uploads should no longer have this problem.
