Segfault when retrieving info from QSettings

[codeslicer]

Just in case, attached is the relevant code:

main.cpp

int main(int argc, char ** argv)
{
...
	QCoreApplication::setOrganizationName("app");
	QCoreApplication::setApplicationName("appmakers");
	QCoreApplication::setOrganizationDomain("app.com");
...
	return app.exec();
}

int main(int argc, char ** argv)
{
...
	QCoreApplication::setOrganizationName("app");
	QCoreApplication::setApplicationName("appmakers");
	QCoreApplication::setOrganizationDomain("app.com");
...
	return app.exec();
}

	return internalAppSettings->value("main/info", "default").toString();
}

#include <QtCore>

settings::settings(QWidget * parent) : QWidget(parent) {

Personally I don't see anything wrong with this... Yet I still get a segfault:

Symbol this is a variable with complex or multiple locations (DWARF2), length 4.

This is really weird Any hints?
