If the user saves a video before the artwork has been downloaded into the temp folder (at least I'm pretty sure those are the conditions for this bug), the save process breaks, because it assumes the file is already downloaded, and tries to do a file copy on the remote URL (appended to the local src directory, nonsensically), which obviously doesn't work.
