Description Hugo Parente Lima 2010-01-21 17:32:04 EET

The warnning:

ISO C++ says that these are ambiguous, even though the worst conversion for the
first is better than the worst conversion for the second.

is a error on some versions of GCC. You get this warnning on
qbytearray_wrapper.cpp

Confirmed. It builds now successfully on Mandriva 2009.1 and openSUSE 11.1.
