I'd say: Yes, there might be (note the version (4.6.2) he is using).

There was a race condition issue with QString and QHash involved in 
versions up to 4.8.x which had to do with the Latin1 and ASCII 
conversion of QStrings.

If you are using multiple threads, it might be an approach to verify the 
problem with a more recent version of Qt.
