Memory leak using iconv_open

If one uses fromAscii() and toAscii() to convert between char* and QByteArray, it all works fine without the line below:
QTextCodec::setCodecForCStrings( QTextCodec::codecForLocale() );

With it, one gets memory leaks, as reported by Valgrind. In qiconvcodec.cpp:

if (iconv(cd, &inBytes, &inBytesLeft, &outBytes, &outBytesLeft) == (size_t) -1)

{ perror("QIconvCodec::convertFromUnicode: using ASCII for conversion, iconv failed for BOM"); return QString(uc, len).toAscii(); }

return is called without iconv_close() first.
