Occasional Gstreamer issue using 2.3.2

[DavidOpgh]

Getting the gstreamer segmentation fault occasionally.
For now doing a single reboot will make Rocket Show work correctly.
What's interesting is that the fault only occurs on my "main" version of Rocket Show.
My second "remote" PI that I have set up and gets called remotely by the main PI hasn't generated this error even though they both use the same default composition.
