OK, thanks.  I have 4fbabd9 running on the F30+nVidia+TV box with no 
segfaults or new functionality problems seen so far.

5.3.13-200.fc30.x86_64, nVidia 440.36, GeForce GT 710/PCIe/SSE2

nvdec came up in the second launch of the frontend, and the widget still 
says it does not have a window, but...   Now for el7.

Great,

John
