Survival Mode, Normal difficulty.
Silverfish Spawner contains Pig and does not spawn anything.
a "newly discovered" (I just found it, but it is inside a chunk that has surely been loaded before) Dungeon Spawner is also filled with a Pig.
Other spawners, a Blaze Spawner and a Zombie Spawner (previously a Skeleton Spawner, and yes, I'm still really salty about that) work fine.
This is current version, latest update.
