Okay, still a short answer, before I go to bed.

That is really strange. Are you sure the file is intact? Did you compare it 
with a known good backup? You have been able to use it before on Ubuntu 14.04, 
haven´t you? So in this case I would dig out an older version of the file that 
works. The one directly before the first attempt to migrate anything. This one 
should really still work with an KDE SC 4 based distro, cause you used it 
before like that. Heck, if nothing else works, why not restore your Ubuntu 
14.04 completely (system + userdata, at least what is needed for KWallet) in 
order to access your passwords.

You could look in kwallet sourcecode.

I´d ask this in IRC, in kde-devel / frameworks-devel mailinglists. I do not 
have the impression that many KDE developers read this mailinglist regularily.

Good luck.
