Description:
There is problem with file sorting in category on Commons (see http://commons.wikimedia.org/wiki/Category:Gerbovnik_Vinklera). Newly uploaded files appeared after set of old files. Names are on Cyrillic, but it's possible to notice first letters appeared in 2 places.
This problem was introduced after upgrade to 1.17.
It may be MediaWiki problem, or some database tebles was not properly updated during/after upgrade.
Version: unspecified
Severity: normal
Due to changes at the category system the namespace is not any more inside the sortkey. All files uploaded before the 1.17 have the old sortkey with namespace.
You can fix this by nulledit (save without changes) all the pages inside the category.
With the api you get the sortkey:
http://commons.wikimedia.org/w/api.php?action=query&list=categorymembers&cmtitle=Category:Gerbovnik%20Vinklera&cmprop=sortkey&cmlimit=500
Note, the category changes in 1.17 aren't live yet. Presumably this is caused by the category changes being patched out, but the removing of $wgCategoryPrefixedDefaultSortkey in r70416 still (Accidentally?) kept in. It should all be fixed when category collations are deployed to wmf.
