And this actually happens in the extcap programs when "data_file_url" is
called to obtain the help page. Stack trace:

    started_with_special_privs () at wsutil/privileges.c:153
    get_datafile_dir () at wsutil/filesystem.c:841
    data_file_url (filename="randpktdump.html") at wsutil/filesystem.c:2178
    main (argc=3, argv=0x7fffffffe118) at extcap/randpktdump.c:139

Patches welcome I guess.
