What then of collision problems in github's shared backend?

This appears to have been due to a corrupt repo, so not a legit collision.
Repos can be constructed with what look like colliding objects. Git's "SHA1 COLLISION FOUND" is triggered if 2 objects with the same sha appear to have different sizes or types. This can easily happen due to corruption; flip a bit in the type and a tree object seems to be a colliding blob object.
