Bug 909150 – media-sound/musescore-4.0.2: crash with error "ERROR | main_thread | EngravingModule | onInit: Fatal error: cannot load internal font :/fonts/musejazz/MuseJazzText.otf"

• Product: Gentoo Linux
• Status: UNCONFIRMED ---

[Description BurnyLlama 2023-06-25 10:06:18 UTC]

When trying to launch Musescore 4 it crashes. If you try to launch it from the terminal you will find the error:

```
QEventLoop: Cannot be used without QApplication

```

Reproducible: Always

Steps to Reproduce:
1. Launch Musescore 4 (via terminal)
Actual Results:  
It segfaulted with the error provided in `Description`.

Expected Results:  
I expect it to be able to load the font and launch properly.

I chose severity `Critical` since that description contains "crashing", however it should be noted that Musescore is not a system-critical program, so the actual severity of this is quite low.

It should also be noted that the official AppImage works.

I have also tried re-emerging Musescore, but the issue persisted.

I believe the error is caused by the font in question not being properly "compiled in"/included in to the binary.

I don't yet know if this is an issue with the ebuild for Musescore or with Musescore itself. I, however, can't find this issue listed in Musescore's bug tracker.

Ouput of `emerge --info musescore`

I just finished compiling Musescore directly from the upstream source. There it works as expected.

I compiled created a `build_overrides.cmake` as per their (Musescore's) instructions:

```
set(ENV{QTDIR} "/usr/lib64/qt5/") # or wherever Qt is located
```

And then ran:

```
./build.cmake -G Ninja
./build.cmake -G Ninja run
```

And the application launched as expected.

This makes me believe there's an issue with the ebuild. I will try to look more into it later...
