There was an error with the FairPlay DRM signing process that lead to a lot of app binaries becoming corrupt; people would go to download updates from the app store, and after doing so would be completely unable to launch the app. Not even a splash screen or a display of the freeze-dried screenshot from multitasking.

Marco did a really good job of cataloging it because Instapaper was one of the affected applications: http://www.marco.org/2012/07/04/app-store-corrupt-binaries http://www.marco.org/2012/07/04/app-store-corrupt-binaries
