Why haven't I seen any ghasts in the nether?

Question

I don't know if it only happens to me but I can only find pigman. Could it be a bug or certain seeds don't spawn ghasts?

I've tried looking for them around the nether and have not found any.

FYI - My server.properties option for monster spawn is set to true. No peaceful mode is off and it's a SMP map.

How could that happen?

SCREENSHOT AS REQUESTED

So as you can see only pigman in sight.

It isn't your seed, they don't affect mob spawning. Do you have any mods?
Start building a precarious walkway over lava. In my experience, ghasts will suddenly show up just to spite you.

Get out in the open

Start digging tunnels and look for a BIG AREA (the ones that involve lots of lava).

A Ghast can spawn in a small area but the chance is very small compared to a big area...

@Warface: That's not really constructive, can you upload a screenshot/world? – Tom Wijsman Sep 9 '11 at 22:29

If you generated the world before the 1.2 patch, there is a chance of them spawning above bedrock, assuming you have been there.

Right, any areas of the world generated later than this, however, will not follow this rule. – GnomeSlice May 24 '12 at 3:20
