Buttons on QMessageBox not sized correctly if style sheet with min-width is applied.

The width of QPushButtons on a QMessageBox will not size large enough if a style sheet with 'min-width' is applied. The expectation is that the push buttons will be no smaller than min-width but should be able to expand to a large size.

See code:

#include <QtGui/QApplication>
#include <QMessageBox>

int main(int argc, char *argv[])
{
QApplication a(argc, argv);
QMessageBox optionDialog(QMessageBox::Question, "Test Dialog", "Please Select an Option", QMessageBox::NoButton);
optionDialog.setStyleSheet("QPushButton

"); //<-- Dialog will size correctly if this line is commented out
optionDialog.addButton("Test", QMessageBox::AcceptRole);
optionDialog.addButton("Test a very longgggg text", QMessageBox::AcceptRole);

return optionDialog.exec();
}
