Importing model with animations from blender

So… i made this model last night, textured it, rigged it and i tried to animate it…
So i made a really basic walk animation in blender.
It looks perfectly fine in blender, but when i import it into unity, one of the legs keeps rotating on the wrong axis.

I tried deleting all the keyframes and make it all over again. Same problem.
I tried deleting all the keyframes and making only 2… same problem.

Well, when i export it as a .blend file it works fine.
It doesn’t work with collada or fbx files for some reason.
