How-to decrypt data.tar.gz.enc offline on linux ?

So, just to get it right. If you try to restore the both(apk&data) or only apk it works just fine, but if you try to restore only data then it gets such an error?
The Data seems to have another structure from what I'd excpect from Gmail. Does this happens to other apps or only to couple of them? if yes, could you list them here. Thanks.
