QSystemTrayIcon balloon text color is light on a hardcoded yellow ballloon, so it makes it almost invisible to read.

On ubuntu version 10.04 with a dark theme like "darkroom" on a GNOME desktop, the qsystemtrayicon displays yellow balloons with white text.
I guess this bug was already raised a while back and has been changed to fixed in QT4.5, but this does seem to reappear for me while using QT4.7.
The same examples in the bug report for http://qt.nokia.com/developer/task-tracker/index_html?method=entry&id=214171
is valid.
