Line break tokens in text ignored when using font capitalization AllUppercase or AllLowercase

Using
void QPainter::drawText ( int x, int y, int width, int height, int flags, const QString & text, QRect * boundingRect = 0 )
with flags = 0 or any combination of flags does not print new line.
In qt 4.4 it works fine, drawing new line when "text" contains the new line character.
