Funny you should mention this. Just yesterday I was feeling the tail of my pouch (hollister two-peice) and found for the second time that the pouch had a small air bubble in the lining. I know for a fact that it did not have this when I put it on new (9 days ago) so it must have something to do with use. I was guessing two possibilities;
1. the lining becomes seperated when folding and unfolding the tail causing a bubble between the layers of plastic or
2. since I use peroxide to control smell it might have something to do with that many days of a capful of peroxide affecting the plastic.
I piched the bubble between my fingers a little too hard and it popped just like the plastic wrap bubbles. This concerned me but it didn't develop any leak so I guess since it is between the layers it didn't create a path to the outside world thank goodness. And for anyone wondering, yes 9 to 10 days is my normal wear between changes, just lucky I guess, LOL.

Yeah the one I accidentally popped yesterday didn't develop a leak at all or even odor. Since you say you are getting them toward the top also then I guess maybe my peroxide theory might be more on the mark. All I can guess is the peroxide is causing some reaction between the layers of plastic and traps air in there. With hollisters it takes till about day 7 or so for me to notice them forming. Not sure but that is my best guess about what is going on.
