Imagick::whiteThresholdImage
If you are trying to manipulate a uploaded file and then save the file all in the same request with Apache + mod_dav this will fail.
mod_dav puts a lock on the file during the request where the file is uploaded so trying to save the smallest file, e.g. 1kb will fail with a "Failed to allocate memory" error.
