Comment:

 A very similar issue happens with tags. To replicate:

 - Create a post tag named "0" (just the number without quotes).
 - Add this tag to a few posts
 - Go to WP-Admin > Tags and the "Count" column in the "0" row will display
 the number of posts with this tag. Click on this number.

 Now instead of displaying posts with the category "0", no posts are
 displayed.

 For the categories, I used the `array_filter()` with the callback @jesin
 suggested. For the tags I suggest an enhanced test instead of `! empty(
 $q[ $t->query_var ] )`.
