When I set a squid mobspawner on a void map, the spawner don't work, the squid don't spawn but the others spawners work with success.
If you want, i've already create this world.

Not a bug.
You've placed the spawner too low:
http://minecraft.gamepedia.com/Spawner :
Squid spawners now only work in a narrow elevation range, from 46 to 62.
Please attach a zip of that world to this ticket. The external download link doesn't work.
