Details

Description:
The program segfaults due to a call to `wxTranslations::Get()->SetLanguage(wxLANGUAGE_DEFAULT);`, it turns out that `wxTranslations::Get()` returns nullptr in this context.

Additional info:
This is unique to the wxwidgets/superslicer combination used on archlinux in particular; the upstream precompiled version works fine out of the box with its bundled wxwidgets.

Maybe related upstream bug: https://github.com/prusa3d/PrusaSlicer/issues/8299

I recompiled the superslicer package with debug symbols to get this backtrace:

```

Steps to reproduce:

* Update to the specified package versions
* Run superslicer
* The program crashes with a segfault

Might need similar treatment as per prusa-slicer fix [1] ?

As superslicer is a prusa-slicer fork, yeah.

Applied Bruno's fix, thanks.
