With the option "stop_on_error" I have problems with redirection. E.g. when entering a new bugnote, after pressing enter I am left at an empty "bugnote_add.php" page.

I tried to trace the problem, and found that
print_successful_redirect -->
print_header_redirect

Stops at
if ( ON == config_get( 'stop_on_errors' ) && error_handled() ) {
return false;
}

Even though there was no error, it seems as if "error_handled()" returns false. Is it possible, that it returns false, if there is not error and no handled error? The default for "g_error_handled" is false.

Changing the setting for "stop_on_error", everything worked fine. So I think it is not one of these annoying "additional newline at end of file" problems.
