Comment (by Chouby):

 Hi!

 I started to debug since I am the author of Polylang.
 Here is the content of {{{$this->tax_query}}}:

 {{{
 Array
 (
     [post_type] => post
     [lang] => all
     [posts_per_page] => 20
 )
 }}}
 {{{$tax_query_in_and}}} is just an empty array at this point.

 For you to get the full picture, I unset the query_var 'lang' in the
 parse_query action. Up to now it was sufficient to remove the tax query I
 wanted to remove from the query.

 Maybe that's not sufficient anymore.
