So from my experiments if I uninstall and then redownload, I can download before it updates the resource pack (shows purple crystals underground instead of pumpkin field currently). Typically the resource pack updates by the time I've downloaded one mash up pack. If I reinstall, then wait for the resource pack to update, then try and download it gives the not enough space issue straight away. My guess is something in the resource pack changes folder permissions on the temp folder (based on the errors given when turning on the debug logging).
