I changed the application locale because I wanted to do some screenshots in English. I did it through the Help menu, the closed the application. Now, every time I start it, it crashes before showing any window. There isn't even a drkonqui crash window, just some info in the konsole: stefano@neon:~/.local/share$ kontact -v Icon theme "gnome" not found. kontact 5.7.3 stefano@neon:~/.local/share$ kontact Icon theme "gnome" not found. KSycoca unavailable. Kontact will be unable to find plugins.

I don't even know where to look to restore to default its locale.
> KSycoca unavailable. Kontact will be unable to find plugins. This message indicates a deeper problem. I suggest to ask in a forum of your distribution how to investigate this issue. It might be unrelated to locale configuration.
