Did you download the blockchain with the same Linux version or via Wine/Windows?
New git-repository: I started syncing on Windows 10 with Slim236000.7z from http://www.slimcoin.club, on ubuntu 14.04 with an existing blockchain from slimcoin-0.3.2.1. Syncing from scratch not tested.
Syncing from scratch and fully compiling (slimcoind & slimcoint-qt) works for me on ubuntu 14.04 with slimcoin-0.3.2.1 source from kryptolab.
