Single image field cuases error after upgrade to latest version (3.0.137)

Hi,

I have a image field which set limit to 1 and it works fine until I upgrade the core to 3.0.137.

Everytime I try to upload a image to the field, it causes the following error:

Recoverable Fatal Error: Argument 1 passed to ProcessWire\Pageimage::setOriginal() must be an instance of ProcessWire\Pageimage, null given, called in /home/web/processwire/WireCore-3.0/core/PageimageVariations.php on line 257 and defined (line 1334 of /home/web/processwire/WireCore-3.0/core/Pageimage.php)

When I reload the page and try to edit the page, the backend looks like the following screenshot. The old image is not deleted. And I found that the image record still exists in the database.

Any clue is welcome.

Seem this is a bug when set limit to 1. I will file a bug report to github.
