Exporting FBX from blender only brings some of the actions with it

I'm trying to export an FBX consisting of an armature, a model, and six actions. but whenever i import the fbx into unity, the animations tab only has 2-4 of those actions. so far i can't see a consistent pattern in it.

has anyone come across this before? what might be wrong?

 

Could you give an example image of your export settings?

 

we seem to have gotten it working by changing the version from binary, to ascii. i gues the ascii exporter is just more stable :/
