That is the correct path in the terminal output... /run/user/1000/gvfs/smb-share:server=unraid2.local,share=tv series/Archer/Season 8/Archer.2009.S08E08.REPACK.HDTV.x264-SVA[eztv].mkv As a test I moved it to a different folder that had no spaces in the path Example: /run/user/1000/gvfs/smb-share ...

So, I'm having this problem as well and I'm thinking it has to do with spaces. I moved the same file to another network location/folder that had no spaces and drag/drop worked just fine.
