So, test the archive or check the md5.
That's not actually the case it must be some problem with the way Clockwork Mod flashes these packages because this one is the only one that can fail 3 times in a row and on the forth time succeed and work just fine. I don't quite know what happens as it is unpacking the files and adds the apk file into the system folder but it seems at least for me that it encounters an error couple of times before it works fine.
