Failed to load plugin '/usr/lib/x86_64-linux-gnu/gstreamer-1.0/libgstlibav.so': /usr/lib/x86_64-linux-gnu/libharfbuzz.so.0: undefined symbol: FT_Get_Var_Blend_Coordinates

Hi, 


I am new to Psychtoolbox and I am working with the scripts located in: .../psychtool/Psychtoolbox/PsychDemos/MovieDemos. 

There is a WARNING coming up when I am trying to run the SimpleMovieDemo.m, which is:


GStreamer-WARNING **: 15:38:51.267: Failed to load plugin '/usr/lib/x86_64-linux-gnu/gstreamer-1.0/libgstlibav.so': /usr/lib/x86_64-linux-gnu/libharfbuzz.so.0: undefined symbol: FT_Get_Var_Blend_Coordinates


Gstreamer is installed along with harfbuzz library (libharfbuzz). 


any ideas on how I can resolve this issue?


Thank you in advance for your time!
