EDIT: as Giardini says, not an issue, as the "unwound" bit is the second spring, not the loop around the bolt
If the lose end in the pic is the only bit of spring going around the upright bolt, then yeah, this is a problem. Even if the wheel feels secure, the camber is probably waaaaay out, and even if it feels secure with the car jacked up, driving puts much bigger loads on things then you can with your arms, so the wheel might slip an inch inward (for instance) while driving/cornering, which will do properly weird things to your steering and generally stability.
Come to think of it, if the camber is out, so will be the steering angles
