[3dprinter-general] Bug#1020702: prusa-slicer: SEGV on start

[Bernhard Übelacker]

Hello,
it looks like following line should expect the Get() call returning a nullptr,
which wxWidget documentation explicitly notes.

    2079                    wxTranslations::Get()->SetLanguage(wxLANGUAGE_DEFAULT);


I have raised this question to upstream here:

    https://github.com/prusa3d/PrusaSlicer/issues/9024

Kind regards,
Bernhard
