The "view is null" stuff is normal. What's really concerning is the "Cannot 
paint on null pixmap" generated in QPainter::begin(). That message doesn't 
appear when removing the system tray and adding it back, which is of course 
one way to get the icons to appear again. Commenting out the line 
m_background->paintPanel(painter) causes that message to go away which tends 
to imply that there is a problem before we even get into the SystemTrayWidget 
domain.
