opening files with bluefish -n confuses window title

Ubuntu defaults to opening files with bluefish in a new window. When bluefish first starts it works fine, but when you open a second file it results in a window with an 'Untitled' header even though it contains a saved file. In addition opening a file that is already open results in a window with an untitled document. To clarify I open files in nautilus, not in bluefish's integrated file browser or the file open dialog. This is fairly annoying because it results a bunch of 'Untitled [X] - Bluefish' entries in your taskbar, which aren't too descriptive.
