Description Zeljan Rikalo 2011-02-03 11:30:17 UTC 
Version:           unspecified (using KDE 4.6.0) 
OS:                Linux

oxygenstyle.cpp 
bool Style::drawIndicatorButtonDropDownPrimitive( const QStyleOption* option, QPainter* painter, const QWidget* widget ) const

crash line 3764 because tool is null (and there's no check if it's null).
if( tool->popupMode()==QToolButton::MenuButtonPopup )

So possible fix is
if (tool && tool->popupMode()==QToolButton::MenuButtonPopup )


Reproducible: Always

Steps to Reproduce:
Try to draw an CC_ToolButton on simple QWidget
