mate-display-properties crashed with SIGSEGV in gdk_event_apply_filters()

[Eliah Kagan]

On an Ubuntu MATE Utopic amd64 system in a VirtualBox VM with Guest Additions 4.3.16_95972 installed, mate-display-properties (provided by mate-control-center 1.8.2+dfsg1-1) crashed. I opened it up with System > Preferences > Monitors, the application window displayed momentarily, then disappeared. When I ran it again the same way, the crash did not occur.

Some updates were being installed at the time of the crash (I was running "sudo apt-get upgrade"), so perhaps that is related. mate-display-properties was not one of the packages being updated. I'm attaching possibly relevant information as term-veryshort.log (just some relevant text copied from the terminal) and the usual APT and dpkg-related log files.
