Or people who use a "mixed tabs and spaces" indentation, e.g. size 8 tabs with 4 characters wide indentation, and spaces for uneven indentations. (Which IMHO is broken because it leads to unreadable code when you don't have the same settings as the person who wrote the code).

Also, I guess C-style block comments could cause an over-counting of spaces (but looking at the numbers, it seems that either the query takes this into account, or C code simply has a poor comment-to-code ratio)
