Help contents file not found

[Tim Duncan]

Just installed the games-minesweeper package via apt-get and game plays fine. However, when I go to Help > Contents then Firefox opens with a page:

File not found
Firefox can’t find the file at /usr/share/sgt-puzzles/help/en/index.html.

And when I go to Help > Help on Mines then Firefox opens with a page:

File not found
Firefox can’t find the file at /usr/share/sgt-puzzles/help/en/mines.html.

If I browse in Files to /usr/share/sgt-puzzles/help/en and double click either index.html or mines.html the same error page comes up. However, if in Firefox I go to File > Open File and open index.html or mines.html the page opens fine. Permissions on all files in the folder are: RW-R--R--
