Yes, I have those packages. I used gnome-specimen to see which font is used to render "∑" character and the only font which contains a glyph for "∑" with a wrong shape is "Symbol". ttf-symbols-replacement package (recommended by wine1.2) contains this font and removing that package solved the problem.
