Fatal error with import from Blender

I'm having trouble with Unity's FBX importer and Blender. No matter what I try, including both allowing Unity to automatically convert the .blend file and exporting it manually with various combinations of options, when I try to add the imported asset to my scene, nothing but an apparently empty object appears and I receive the following error message:

!sh->m_AABB.IsValid() UnityEditor.InternalEditorUtility:CalculateSelectionBounds(Boolean) UnityEditor.InternalEditorUtility:CalculateSelectionBounds(Boolean) UnityEditor.Tools:get_handlePosition() UnityEditor.MoveTool:OnGUI() UnityEditor.SceneView:DefaultHandles() UnityEditor.SceneView:OnGUI() System.Reflection.MonoMethod:InternalInvoke(Object, Object[]) System.Reflection.MonoMethod:InternalInvoke(Object, Object[]) System.Reflection.MonoMethod:Invoke(Object, BindingFlags, Binder, Object[], CultureInfo) System.Reflection.MethodBase:Invoke(Object, Object[]) UnityEditor.HostView:Invoke(String) UnityEditor.DockArea:OnGUI()

[....\Runtime\Camera\UnityScene.cpp line 91]

I would gladly use some other software, as Blender isn't my program of choice to begin with, but Unity seems to be really picky about the FBX format for anything with a skinned mesh and I don't have billions of dollars to spend on something like Maya.

If you are exporting your FBX with any other objects than that of your skinned mesh and your rig/armature(so your camera, any stray empties, etc), I'd recommend deleting them from your file and re-exporting & importing. This has worked for others before in some cases.

Also, just in case you're using the new Blender 2.5x, I'd recommend using/exporting form Blender 2.49b, as some of the 2.5x builds have broken FBX exporters.

Luckily for me, patience has paid off and the problem is now moot. The new version of Blender, 2.5, has been under continuous development all Summer and the new 2.54 Beta is able to export FBX files properly. I was glad to see that it had no problems with models, textures, or bones (I haven't tried animations yet). There does seem to be one small glitch - every once in a while my character will disappear from the Scene and Game views, but it comes back when I select it in the hierarchy, so this doesn't seem to be any real problem.
