Its not uncommon for painted Semogue handles to crack eventually (both of mine have), but not when they're brand new. I'd contact the vendor you bought it from and ask for a replacement.
My Semogue 1305, bought from a vendor here, cracked within a month after purchase. The vendor promised to make it right - I declined as he was just getting into selling Semogues. But I would not buy another Semogue with a painted handle and urge others to consider this known issue.
