Have used this utility with inkscape for over a year with no problems. Today it keeps quitting unexpectedly even when I closed inkscape. I get this message: Process: X11.bin  Path: /Applications/Utilities/X11.app/Contents/MacOS/X11.bin Identifier: X11.bin Version: ??? (???)

Any help would be appreciated.
