TagLib::String to QString

[Surya Kiran Gullapalli]

 I'm a newbie to TagLib. I'm using TagLib (1.7) along with Qt (4.7) on
ubuntu   11.04. When trying to access Tag information from mp3 file
and displaying
   the same, I'm experiencing a crash in conversion of TagLib::String
to  QString. I've tried

   TStringToQString (s), QString::fromStdWString(s.toWString()) functions.

Both of them failed. I've looked thru the mailing list archives, with
little success. How to fix this ?
   Thanks,
   Surya
