The patch to org-eldoc applied in b2b587387 still throws an error:

eldoc error: (void-function nil)

I was unable to step through this because (I think) eldoc causes 
the debugger to close as soon as input is received. The error 
occurs when `eldoc--invoke-strategy` attempts to funcall 
eldoc-documentation-default.

The attached patch works for me, but I do not know if it is the 
correct solution.
