Why is it related to asm.js? It's related to PB mode and offline cache.
Besides a .metadata file there is only an asmjs directory, that's why I figured that it has to do with asm.js ;) At least, tat explains why I did not find the other bug. Sorry for spamming the bug tracker.
np, it's better to report a dupe than to not report a bug. :)
