Images under 150x150 pixels fail to be processed which results in a backbone error when trying to add them to your content

As the title says, any image I upload under 150x150 will not be processed correctly (although it shows up in the Library).

When selected, it will then throw a JS error in load-scripts.php saying: "Uncaught Error: A "url" property or function must be specified", which looks like a backbone error.

Any image over 150x150 works fine.

Scratch that, it was actually a plugin not retrieving the right dimensions (it tried to get thumbnail sizes, when none were available).
