Reprocable on Windows 8.1, MAC 10.10, 10.8.5
Description
Hi there!
After porting our applications from Qt 5.4.2 to 5.5.0, I have strange crashes concerning icons coming from the QFileIconProvider set in QComboBoxes. Luckyli for me I can reproduce the crashes with your 'basicdrawing'-example, where I put two icons into the first two entries of the shapeComboBox, just changing the following lines of window.cpp:
//! [1] Window::Window() { QFileIconProvider provider; QIcon icon(provider.icon(QFileInfo("c:/Users/Harro Pahl/Pictures"))); QIcon icon2(provider.icon(QFileInfo("c:/"))); renderArea = new RenderArea; shapeComboBox = new QComboBox; shapeComboBox->addItem(icon, tr("Polygon"), RenderArea::Polygon); shapeComboBox->addItem(icon2, tr("Rectangle"), RenderArea::Rect);
This leads immediately to a crash when painting the combobox via QComboBox::paintEvent (the stack and variables are added as jpg to this ticket).
Thanks for your investigations in advance and greetings from Kiel!
