@Prod: can you provide a command line which produces this issue?

I'm not sure about generating a command line script, but the code pywikibot.Site().allpages(namespace=6) generates the error from strategywiki.org when logged in. It should return 5000 results (per query), but instead it errors around 173.

Pretty sure the Files with wrong extensions are ignored. But unfortunately it seems that all files after them are also ignored instead of just skipped (or giving a Page object back).

Maybe the reason is that update_page can raise

raise RuntimeError(
    f'"imageinfo" found but {page} is not a FilePage object').

The file extension is invalid but here is an imageinfo given.

I tested this change and my script did complete, thanks! I didn't validate how the files with invalid extensions were handled, but it's a minor concern.
