From epan/prefs.c:

        /*
         * Make sure that only lower-case ASCII letters, numbers,
         * underscores, and dots appear in the preference name.
         *
         * Crash if there is, as that's an error in the code;
         * you can make the title and description nice strings
         * with capitalization, white space, punctuation, etc.,
         * but the name can be used on the command line,
         * and shouldn't require quoting, shifting, etc.
         */

So change the preference names to use only lower case.
