No, there's nothing inherently wrong with it.

With some recessive traits that people are unsure about, they breed back to the same line to "prove out" the trait as being genetic.

Technically "line breeding" is breeding to another animal in the same lineage(mom to son, dad to daughter, aunt to nephew, etc). If there is any unwanted genes, it can "double up" and be expressed or expressed more. If there are wanted genes, same principle.
Honestly this is what had been bugging me about morph breeding [especially "Super" types] for a long time; I still don't think I'd be comfortable purposely inbreeding/linebreeding if I had my own, maybe I'm weird ^^;
I do recall, a few years ago, stumbling onto a GTP or Emerald Boa breeder's webpage back when I was reading up on snakes, and they had a lot of hatchlings for sale that were missing one or both eyes, which I thought was caused by inbreeding so that was a huge turn-off for me ._.

Thanks for this thread and all the informative replies, I understand a bit more about this sort of issue now :3
