Org lint and Haskell source code blocks

Org lint and Haskell source code blocks

[Dominik Schrempf]

Hi,

whenever I have a Haskell source code block in my Org mode file, and I execute
=org-lint=, I get the following error:

#+begin_quote
Debugger entered--Lisp error: (wrong-type-argument listp :any)
#+end_quote

(This was obtained with a minimal file just having:
#+BEGIN_SRC haskell
inc n = n+1
#+END_SRC
)

Do you have an idea about what could be the problem? =org-lint= works just fine
in other buffers without Haskell code blocks.

Please find the full error message below.

Thank you,
Dominik
