Description:
Two long files on Wikipedia suddenly doesn't print thumbnail :
https://fr.wikipedia.org/wiki/Fichier:Les_derni%C3%A8res_notes_r%C3%A9dig%C3%A9es_par_Robespierre,_saisies_chez_lui_le_jour_de_son_ex%C3%A9cution_34_sur_34_-_Archives_Nationales_-_AE-II-1419_pi%C3%A8ce_a_et_f.jpg
https://en.wikipedia.org/wiki/File:Gravure_représentant_le_tableau_de_François_Gérard,_"Le_sacre_de_Charles_X_à_Reims,_le_29_mai_1825"_1_-_Archives_Nationales_-_AE-II-3886.jpg
The thumbnails are fine on Commons, and there is no issue on thumb.php.
Instead, the issue is the URL printed on the local wiki thumbnail:
Instead of <dimension>px-<filename>.<extension>, it prints
<dimension>px-thumbnail.<extension>, replacing the filename by
"thumbnail".
A French Wikipedia user asserts it were correctly printed at least 4-5
days ago, but not since yesterday.
I'm not sure if we're in an ops case, or if this is a bug.
