Description
Creating QFontDialog delegate editor will make the application crash with some styles on Qt 4.8.4. With Qt 5 the application takes 100% CPU. The crash can be seen at least with QWindowsStyle and QMotifStyle, the application works fine with QCommonStyle.
It looks like there’s something wrong with the QItemDelegate::updateEditorGeometry.
Attached an application that reproduces the issue. Attached also the call stack of the crash.
