I'm not using symbian so I can't replicate this. However I would add some debug lines in to show what font information is being used (font, pitch, size, etc... ). It may be that setting a font
StyleStrategy like QFont::NoFontMerging might clear that up. Qt uses a best guess when it can't figure out pitch or font size and sometimes this isn't always the best answer like in your case here. Best I can offer.
