Comment (by IwanLuijksQuestMedia):

 What is the status of this ticket?

 I currently still run into this issue (on the search page), using an array
 of terms for the taxonomy in the querystring, like so (where 'country' is
 added to the querystring through a form submission using the GET method):
 country[]=nl&country[]=de

 The search actually does work, but causes a number of PHP errors:

 {{{
 Warning: strpos() expects parameter 1 to be string, array given in
