GetCropUrl in itself is just a string building mechanism. There are overloads that look for a file path in the umbracoFile property on an IPublishedContent representing the media. If that's null, GetCropUrl would likely throw a NullReferenceException.
The resulting URL would also need to "find something". Here's a couple of useful links describing how Umbraco finds the files:
Does GetCropUrl always throw exception if file is not existing on physical path?
We encounter the following error on 8.0.2. is it handled on earlier version/s?
System.ArgumentNullException: Value cannot be null. Parameter name: mediaItem
