 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.
