On dewiki the imagelinks tables contains values like "Bild:<imagename>" at il_to although the page source correctly contains [[Datei:<imagename>]]. The image namespace prefix must not be add to the il_to value. If you are doing a null edit using index.php the wrong entry is deleted. But we made a null edit on all pages and there are some few news ones every day. You can find examples on the missing file reported created twice a week on http://de.wikipedia.org/wiki/Wikipedia:Redaktion_Bilder/Arbeitsliste_Fehlende_Bilder if you are searching for "Datei:Bild:" I don't know the reason, but perhaps there is a single not updated squid or an old mantanace scripts that run on wmf.
The test cases I've checked all involve <gallery>. One of them has a gallery which uses a mixture of Bild: and Datei: namespaces: <https://de.wikipedia.org/w/index.php?title=Haleakal%C4%81-Nationalpark&oldid=96185932&action=edit> The imagelinks table row for the image with Datei: is correct, but the one with Bild: has the prefix. mysql> select il_to from imagelinks,page where page_id=il_from and page_namespace=0 and page_title='Haleakalā-Nationalpark'; +-----------------------------------------+ | il_to | +-----------------------------------------+ | Bild:Kipahulu_coast.jpg | | Bild:Panorama_Haleakala.jpg | | Bild:Panorama_Haleakala2.jpg | | Commons-logo.svg | | Haleakala_National_Park_map_2008.08.jpg | | Haleakala_crater.jpg | | Maui_moku_map_2.jpg | +-----------------------------------------+ It's consistent with the namespaceAliases item in the localisation cache being empty, but the namespaceNames being correct. If Bild is not a recognised namespace, then normal image links would be converted to pagelinks entries, but in a gallery they get put in the imagelinks table. Sure enough: mysql> select pl_namespace,pl_title from pagelinks,page where page_id=pl_from and page_namespace=0 and page_title='Haleakalā-Nationalpark'; ... | 0 | Bild:USA_Hawaii_location_map.svg | ... Probably shares a root cause with bug 31576.
