What do you mean by that?
windows wallet.dat export- import to blockchain.info online wallet - export - import to linux ?

I can see you point, and why it might work - if it was the bitcoin altcoin daemon.

But I am working with a descendant bitcoin --> litecoin --> quark --> C-Notes.

Still, I am almost sure, the problem is already the same even with the greatgrandmother bitcoin, that's why I am posting here.
