Comment:

 Mediastuttgart - Thanks for the report. What you've described is a little
 odd. The logic in question is:

 {{{
 $queried_taxonomies = array_keys( $tax_query_in_and );
 $matched_taxonomy = reset( $queried_taxonomies );
 $query = $tax_query_in_and[ $matched_taxonomy ];
 }}}

 Line 3877 is the last line. It's not clear to me how we could fetch array
 keys on the first line, but then on the last line the system could
 complain that the array key doesn't exist :) Could you do some debugging
 to show the contents of the following variables at this point?
 `$tax_query_in_and`, `$this->tax_query`
