Alright, I think I found the problem. It's the "show desktop" shortcut (super+D). If I have clicked this keyboard shortcut and then bring up nautilus and hover a file over evolution, nothing happens. If I bring evolution up again by clicking on it in the launcher, it works fine. It seems as if Evolution, if it minimised, will not accept drag'n drop files.
