Segfault when retrieving info from QSettings

[wysota]

settings::settings(QWidget * parent) : QWidget(parent) {
	QSettings internalAppSettings(this);
}

settings::settings(QWidget * parent) : QWidget(parent) {
	QSettings internalAppSettings(this);
}

This creates a local variable called internalAppSettings that gets destroyed immediately when the constructor returns. Your member variable is left uninitialized. Try this instead:

settings::settings(QWidget *parent) : QWidget(parent){
  internalAppSettings = new QSettings(this);
}

settings::settings(QWidget *parent) : QWidget(parent){
  internalAppSettings = new QSettings(this);
}

Or better yet simply don't declare "internalAppSettings" as a pointer but instead as a regular object and then leave the constructor empty.
