[clipboard]: gnome-settings-daemon crashed with signal 5 in _XReply()

[JIR]

Seems to happen intermittently when I have Inkscape open. Inkscape usually shows a "uniconverter failed" error immediately before this happens, so I wonder if it has something to do with converting between formats of vector images on the clipboard.
