Segmentation fault on Hyperion 2.0.0-alpha.7

Bug report

Hyperion 2.0.0-alpha.7 crashes after setting up LED hardware with a segmentation fault

Steps to reproduce

1. Flash HyperBian
2. Open Hyperion UI from the browser
3. Setup LED Hardware:
   • LED Controller
   • Controller Type: adalight
   • Output path: /dev/ttyUSB0
4. Save Settings

What is expected?

Hyperion running

What is actually happening?

Hyperion crashes as soon as the Settings are saved. Because by default Hyperion runs as service, Hyperion restarts and crashes again, and again ...

Stopping the service and manual starting hyperiond shows these logs:

From above logs multiple errors occur, not sure if they are related. The zipimport.ZipImportError: can't decompress data; zlib not available error was reported earlier at #881

Removing hyperion.db make Hyperion start again.

@Paulchen-Panther, @Lord-Grey just curious - when is the next hyperionNG release expected?

[Paulchen-Panther]

Keine Ahnung. 😄

[tpmodding]

@RaymondMouthaan no ETA for now...sorry, when we think we are ready...

[RaymondMouthaan]

Well I guess I'll see it coming when the time is there 👍

Thanks to all to tackled this issue, happy its fixed & merged 💯

@Paulchen-Panther your script does not seem to work for me on a RaspberryPi 4:

wget -qO- https://git.io/JUsob | bash -s 991
*******************************************************************************
This script will download a specific Pull Request Artifact from Hyperion.NG on HyperBian
Created by Paulchen-Panther - hyperion-project.org - the official Hyperion source.
*******************************************************************************
---> Pull Request 991 not found -> abort

[tpmodding]

@sh0rez nothing to do with rpi4 itself...the artifacts are only limited time available...

[sh0rez]

@tpmodding The manual steps above work for me – so some artifact is still there.

Are these different ones?

[Paulchen-Panther]

@sh0rez tThe script can only download artifacts from open PRs. 991 is merged and closed. it also makes no sense to test closed PRs.
