Can you post an example of the bug? This works fine for me:

\documentclass{article}
\usepackage{fontspec}
\begin{document}
\setmainfont[
  ItalicFont=HiraKakuPro-W3,
  ItalicFeatures={Style=Italic},
  BoldItalicFont=HiraKakuPro-W6,
  BoldItalicFeatures={Style=Italic},
  BoldFont=HiraMinPro-W6
    ]{HiraMinPro-W3}
test\itshape test\bfseries test\upshape test
\end{document}

Putting the feature into the font name (such as "HiraKakuPro-W3:+ital") 
is bound to cause problems. I highly discourage such practice, even if 
it works some of the time at the moment.

(By the way. I know it's not easy from the fontspec manual to know that 
+ital corresponds to the "Style=Italic" font feature. To be improved 
when I do the big re-write (with proper LuaTeX support) after my 
thesis.)
