Have you tried redirection? 

gpg < bigfile.pgp > bigfile

Using redirection is the correct way of handling large files
regarding both de- and encryption.

I haven't seen this error myself in connection with large files

If you can, try decrypting on the same system the data was encrypted.
Looks like you switched to Kubuntu though...

Maybe someone else will come up with some magic that'll help you.

As a last resort, a fresh compile might help using the exact
programme versions you used on the system your data was encrypted on.

I hope you have additional backups. Always test such critical things
extensively on each system affected (I know it's a pain).
