Short description of error
Tried to import an FBX, got following error.

bpy.context.space_data.system_folders_active = 2
bpy.ops.object.select_all(action='DESELECT')
Python: Traceback (most recent call last):

location: <unknown location>:-1

pirate.fbx (was downloaded from turbosquid if it's matter)

Exact steps for others to reproduce the error
Just tried to import attached FBX into empty project.

Commentary
I tried also the last BETA with same result.
I found old similar bugs here, some of them was marked as resolved. #44806, #43095, #53011
and also found a conversation about similar error on blenderartists where they said, the problem was one of bones, scaled to 0.

I tried it in Autodesk Viewer and it also shows errors, though could render the model:

TranslationWorker-TextureResizingFailed The drawing's textures were not correctly processed.
TranslationWorker-ThumbnailGenerationFailed The drawing's thumbnails were not properly created.

Thing is, there seems to be many issues with this file... We do not have the time to investigate a 20MB binary FBX file, but will add a check/workaround for this error in the importer code for now.

We can only asses whether this is actually a bug in FBX importer, or a broken FBX file, if we get a much smaller reproducible case.
