Blender Export .fbx

Hi,

iam using Blender 2.72 to import a riged character(fbx). Everything is ok and i can save it as .blend.
But i need to export back to fbx. First problem is bones are not linked to meshes,
second problem one bone is “fucked up”.

I tried to use an older blender version with bos fbx import/export plugin, nearly the same result.
So maybe i have wrong export options?

The funny thing: Meshes and bones exported separatly works.
