Describe the issue

I've notice that my temporary storage gets full from time to time. It happens when RC try to scale some images using Imagick and fails, showing the PHP Error.

After that, a file called "magick-xxxxxxxxxxxxxxxxxxx" is left in my temporary storage. Sometimes, there are several very large files like this and the filesystem gets full.

This only happens with specific images and it's not related to the their properties (size, type, ...) because I've tried with several images, with same type and size and I don't always get the error.
