Debug: KGlobal::locale::Warning your global KLocale is being recreated with a valid main component

What does this suppose to mean? Is it possible to fix it?

Debug: KGlobal::locale::Warning your global KLocale is being recreated with a valid main component instead of a fake component, this usually means you tried to call i18n related functions before your main component was created. You should not do that since it most likely will not work

I’ve updated from 11.3 (KDE) to 11.4 and already have 2 programmes (VLC and QGIS) crashing with this message (in concole) after certain actions.

My locale in 11.3 was RU and I changed it to EN before updated to 11.4. After update was finished I changed locale back to RU.
