Hi all,

valgrinding ksiemens (happens with all other apps, too), I see among other 
stuff the following output:

==1786==
==1786== Conditional jump or move depends on uninitialised value(s)
==1786==    at 0x43DA1112: 
LiquidStyle::drawPrimitive(QStyle::PrimitiveElement, QPainter *, QRect const 
&, QColorGroup const &, unsigned int, QStyleOption const &) const (in 
/opt/kde3_1303/lib/kde3/plugins/styles/liquid.so)
==1786==    by 0x43DA6D16: 
LiquidStyle::drawComplexControl(QStyle::ComplexControl, QPainter *, QWidget 
const *, QRect const &, QColorGroup const &, unsigned int, unsigned int, 
unsigned int, QStyleOption const &) const (in 
/opt/kde3_1303/lib/kde3/plugins/styles/liquid.so)
==1786==    by 0x407B5BC1: KToolBarButton::drawButton(QPainter *) 
(ktoolbarbutton.cpp:519)
==1786==    by 0x40D67483: QButton::paintEvent(QPaintEvent *) (in 
/usr/lib/qt3/lib/libqt-mt.so.3.0.3)

I looked into liquid's source code and in drawPrimitive() there's one large 
switch/case statement, which seems to trigger that warning. However, the 
switch() is on the QStyle::PrimitiveElement, something that that seems to be 
delivered by the framework. So, to me it seems the styles are fed with 
uninitialized values, which may lead to strange behaviour..

Can someone with more knowledge about styles and such have a look and proove 
me wrong?

regards,
	matze
