I'd say so. Won't cost much to get fixed (or DIY if you fancy).
In fact, having an Ibanez neck crack fixed next week. And it's a gazillion times worse.
Strictly speaking the split is only in the head, not the neck. As IC says, tricky getting glue in there and in fact I would bet a professional repair would involve cutting slots along the splits and fitting slivers of a similar wood.
I'm after a good 5 string bass and wondered if this might be worth the risk?
