Scalar value variable issues

So we had these problems (at end of post). Fairly noticable.

Deleted everything we could find that could cause it (after making a hackish custom error message setting, see blockquote here)

<pre>function wsf_action_init() {
  set_error_handler('wsf_action_backtrace_error_handler');
}

function wsf_action_backtrace_error_handler($errno, $message, $filename, $line) {
  if ($errno != '8' && $errno != '2048') { //
   drupal_set_message($errno . ' ' . $message);
//   drupal_set_message('Who you gonna call? <pre>' . print_r(debug_backtrace(), TRUE) . '</pre>');  
var_dump(debug_backtrace());
  }
}</pre>

And Agaric's commit messages:

"by george i think i've got it... it's obvious, i don't understand how it really works, but... what the hell nothing from drupal_set_message"
"ok. so drupal_set_message silently fails if too much is stuffed in it"
"drastic testing"
"wow, we isolated the area"
"return the problem"
