I stumbled on this. It doesn't make sense to me. I use XFCE-4, LibreOffice Calc and QMPlayer2 is installed, but I don't use it.

Open any (existing) spreadsheet.
Left click on Files > Properties
then left click on the file location on the properties window (i.e. /home)

When I did that, QMPlayer2 started up on my computer. Did you get the same behavior?
