Wrap drupal_write_record('panels_display', $display, $update); in an if statement

I have spent some time working on making panels thinking that it was something other than code. When I would create panels/pages for any of my children domain it would not actually save anything. I noticed in your "panels_save_display" function you utilize drupal_write_record. My recommendation is to wrap that in an if statement so that if there is error, you also write it to the screen as well as dblog. (As some people might not use dblog). Just a suggestion. It could be a simple:

if(!drupal_write_record('panels_display', $display, $update)){
drupal_set_message(/*error message here*/, 'error');
}

Just a suggestion. Thanks.
