[O] String nil error when export with ":EXPORT_OPTIONS: |:nil" (without exporting table) in properties drawer

[Lei Zhe]

I tried to exclude the table export of one headline by setup:

* headline
 :PROPERTIES:
 :EXPORT_OPTIONS:  |:nil
 :END:

But the string nil error appeared.
Any help?

I am working on Org-mode 8.2.10.
