  • Component changed from General to Upload
  • Keywords has-patch commit added
  • Milestone changed from Awaiting Review to 3.9

We do, however check if it's set in line 223 (added in [12142]), so we might as well do the same here.

Whatever they say, here is the error log from my PHP 5.4. I printed error_log(print_r($file, true));
