Alpha7 Crashes on Fedora 32

• I confirm that this is an issue rather than a question.

Bug report

When trying to start hyperiond on Fedora32 with an adalight device, it crashes. Doublechecked, the arduino I am using has DATA_PIN 6, connected to PC via /dev/ttyUSB0, user running hyperion has access to the port (successfully read the Ada\n magic word from a python console)

Steps to reproduce

• Install alpha7 on Fedora
• Change device to adalight
• Change port to ttyUSB0 (as I don't have ttyACM0) - LED HW is arduino UNO using PIN6 for data output, connected on USB
• Restart hyperion

What is expected?

Hyperion starts and can use the Leds

What is actually happening?

hyperiond crashes

Just adding my 2c, I'm getting this as well instantly after configuring adalight.

Segmentation fault (core dumped)

This is on a x86_64 Ubuntu 20.04.1 LTS machine, not a Pi or SBC.
This is also encountered when I'm root typing hyperiond directly.
