Had a quick look at this,

replacing

context.selected_objects

with

[o for o in context.scene.objects if o.select]

in export_fbx_bin.py line 3058

fixes (as a workaround) the error. For some reason context.selected_objects is returning an empty list on some occasions, especially after start up. This behaviour can also extend to the console, with C.selected_objects returning [] with objects clearly selected.

There is no bug here, in fact what happens is that your 3DView is disconnected from scenes' layers.

context.selected_objects uses Scene's visibility of objects, obviously not some random 3DView one (and hidden objects are never considered as selected).
