Invalid argument supplied for foreach() in imagecrop_reuse_effect() (line 237 of imagecrop.effects.inc).

I have one image style with a javascript crop action for regular pictures in a photo gallery. See attachment: crop_issue_img_style_1.png.

I instructed this same javascript crop to be resused for thumbnails, but to scale the thumbnails down. Trying to select "reuse" renders an error. See attachment: crop_issue_img_style_2.png.

The error continues to show for every gallery page until I disable "reuse."

Whatever the problem is, thought this might be of help.
