no emitting - incompatibility with different modules

I noticed that the emit.php gives me the error

Failed to load resource: the server responded with a status of 400 (Bad Request)

This was cause by the following:

Array to string conversion in *\radioactivity\radioactivity-bootstrap.inc on line 95

a print_r($temp); shows me that the $temp array variable have 2 arrays inside. That comes from linked_field and field formatter conditions. So i have a quick workarraound by adding

unset($temp['conditions']);
  unset($temp['linked_field']);

There have to be added a check routine that filters arrays inside that $temp array.
