I don't know if I'm the only one, but I can't see what you're talking about in those pictures. Is it obviously cracked? If so and it's a mfg defect your warranty will cover it. If it's something you did (clamp too tight?) then the warranty won't work, but the store or the mfg may make it right.
At any rate I would take it back and see what they say.
And, no, gluing will not work.
