This isn't a question at all. I found a problem when I was testing the 1.3.2 build on iOS4 iPhone simulator.
The app kept on crashing after the loading of app.js. By looking at the console crashing stacks, I soon realise that it crashes around the line when a particular eventListener is trying to remove itself.
So I thought this may help someone out there probably with the same crashing problem.
Do not use xxx.removeEventListener at all is probably the best workaround.
Cheers, hope it helps.
Can you post your code? I had a similar issue but found a work around but not using the word 'this' in the removeEventListener.
