In synchronise menu when compare function is invoked against a local (source) directory and a remote target (smb:// share) the following is seen: "Information: smb://<remote Samba share/file#name does not exist" This happens for every file at the local source side that contains "#" character within its filename. I guess this is due to "#" character being reserved for HTML anchors URI schema which doesn't translate well with filenames containing "#" characters.
I think this ticket should be marked as a duplicate of this one: 270150
