Some strange behavior around $all. Unclear to me what is right, but it does seem that 2.5 should not be matching this document. The way I see it is that "a" does not contain the object [""], it IS that object, thus this should not be matched.
In 2.5:
> db.repro.insert({_id: 0, a: [""]})
> db.repro.find({a: {$all: [[""]]}})
{ "_id" : 0, "a" : [ "" ] }
> db.runCommand({buildinfo: 1})
