[Plugin: Query Multiple Taxonomies] Problems with 1.3 in WP 3.0.1

I’ve just upgraded to 1.3 and having some issues with the widget. (using TwentyTen theme)

On the homepage (i.e. no filtering by custom taxonomy) widget displays fine. Click a link from the widget – so now seeing all posts corresponding to a single custom taxonomy term, and get the error:

Warning: array_merge() [function.array-merge]: Argument #1 is not an array in ~/…/wp-content/plugins/query-multiple-taxonomies/core.php on line 161

Line 161 onwards reads:

$args = array_merge( $wp_query->query, array(
‘nopaging’ => true,
‘caller_get_posts’ => true,
‘cache_results’ => false,
) );

Modifying this to

$args = array_merge( $wp_query->query_vars, array(
‘nopaging’ => true,
‘caller_get_posts’ => true,
‘cache_results’ => false,
) );

Seems to fix the error but haven’t tested.

Error doesn’t occur if you jump straight to a view searching multiple terms from custom taxonomies. (makes sense – then you have an array of terms in $query I guess)

Secondly noticed that now in widget it seems to only offer ability to ‘add term’ to current view, not to switch to a view filtered to alternative term – which was the previous behaviour. i.e. clicking anywhere on a term in the taxonomy gives the same action as was previously reserved only for the ‘+’ sign following the term
