Certain texture packs, after updating to 1.7.0, show store-related errors with missing textures

After the latest 1.7.0 update, the Egyptian texture pack also updated, and now it gives an error notification, something about the button to purchase coins in the store is missing. (see screen cap)

I'll let you know if I see this with any other pack. So far, I've only tried Chroma Hills, which is fine.
