Might be a font issue. I already seen bugs related to an incorrect metrics
in DejaVu fonts.

Sure it does. Try inspecting the font's tables and metrics.

I don't think so. You could build Qt with debug symbols and try to debug
harfbuzz-thai.c, though I'd better inspect the problematic font prior to
digging so deep.
