No more access to mate-control-center

Hello,

Once more I tried to count on your helping hand. Not a big issue but when I try to launch the mate-control center I receive this message :

libslab:ERROR:app-shell.c:694:create_application_category_sections: assertion failed: (app_data->categories_list != NULL)
Bail out! libslab:ERROR:app-shell.c:694:create_application_category_sections: assertion failed: (app_data->categories_list != NULL)
fish: Job 1, 'mate-control-center' terminated by signal SIGABRT (Abandon)

I have no clue at all how to fix it. I did a new install but same result.

Thank you
