It first occurred to me that it was just an air bubble, but then it got worse. The rubber base is starting to come off at the front, causing my MacBook to keep wobbling whenever it's in a flat surface :S. My MacBook is still under guarantee, so if I ring up Apple, or even take it to the nearest store, will they fix it? Here's a picture of what the problem is:

I went to my local Apple Store today with this problem and another.
The genius said this is completely covered under warranty and they had the part in stock and could replace it same-day, but due to my other problem it would take longer. Other problem being hair line cracks around the hinge.
My Genius Bar Work Authorization document states the following.
Problem Description/Diagnosis
Issue: Bottom case material is separating from the plastic. Display assembly over hinge is cracked.
Steps to reproduce: Verified issues were not caused by accidental damage.
