Changing (colour) preferences leads to a gtk crash

[digidoor]

Steps to reproduce:

• install endeavorOS (MATE, in this particular case; it's a gtk issue as far as I can tell)
• install wxHexEditor from AUR
• open wx settings and change preferences on colors
• click "Save"
• produces the following error:

/usr/src/debug/wxwidgets/wxWidgets-3.2.4/src/gtk/choice.cpp(303): assert ""Assert failure"" failed in GetString(): invalid index

More specifically, the backtrace:

Same issue on debian 12, but I managed to fix it : I noted that the Language option on the preferences was empty, so I chose one - "English" in my case- , now the prefs can save any chances. HTH

quick fix for anyone compiling.

HexDialogs.cpp:
3138 void PreferencesDialog::SaveRegistry( void ) {
3139 if(chcLang->GetSelection() != wxNOT_FOUND) {
3140 myConfigBase::Get()->Write( _T("Language"), wxLocale::FindLanguageInfo( chcLang->GetString( chcLang->GetSelection() ) )->Description ); //Saves string into configuration file.
3141 }
