Hello again, maintainers,

I was finally able to get Thunar built with debug symbols and started it 
under gdb.  In Thunar, I navigated to a folder in my home directory, 
double-clicked a sound file to play it, then minimized Thunar.  I then 
performed the following commands repeatedly and Thunar crashed while 
sitting unused/idle:

     sudo pkg remove -y smplayer && \
     sudo pkg autoremove -y && \
     sudo pkg clean -ay && \
     sudo pkg install -y smplayer && \
     sudo ldconfig

The gdb output and backtrace are below:
