It looks like this is being caused by a new content type in nsIContentPolicy. When an image is loaded via <img srcset="..."> it is classified as

/**
 * Indicates a <img srcset> or <picture> request.
 */
const nsContentPolicyType TYPE_IMAGESET = 21;

See here

Since it isn't an available content type here it gets classified as Other here.

The MDN docs haven't been updated to reflect the new content type. I ran into this problem when updating Firefox from 36 to 38 while maintaining the same Policeman version 0.18.1.1
