Is the Unity 4 profiler broken?

I was trying to profile my app but didn't understand the numbers I was seeing which led me to testing a blank scene.

Just did the following test using Unity 4 Pro / iOS Pro.

1. Empty brand new project and scene (nothing - removed the camera).

2. Ran the empty scene and did a profile

Looking at the Memory information, I get:

• Total: 52.3MB Delta 0 B

• Textures: 153 / 0.9MB

• Meshes: 15 / 193.3KB

• Materials: 12 / 2.9KB

• Animation Clips: 0 / 0B

• AudioClips: 0 / 0 B

• Assets: 407

• GameObjects in Scene: 0

• Total Objects in Scene: 72

• Total Object Count: 479

This is a completely empty project and scene. Am I reading this wrong?

What are the 153 textures and 15 meshes? According to the rendering data there are no allocated textures.

Thanks.
