Is Apple serving corrupt app store binaries?

Hello,

Despite uploading a fully tested crash-free version of the Paatle iPhone App to the App store, some users experience an app crash immediately after updating the app. It would seem that Apple is serving corrupt app store binaries.

I know that Marco Arment of Instapaper reported something similar a while back which was supposedly fixed, but alas it persist.

Our current workaround is to have users delete and reinstall the app afresh from the app store.

Anyone else seeing this?

Thank you.

Sarah
