Clicking on QPushButton causes force close

Gravitaytion

Everytime I click on my Push Button it stays clicked and the application crashes. I added it with the ui designer.

This is the header of the class that uses the ui:
@#ifndef DARLEHENSRECHNER_H
#define DARLEHENSRECHNER_H

#include <QMainWindow>
#include "Darlehensgeber.h"

namespace Ui {
class Darlehensrechner;
}

class Darlehensrechner : public QMainWindow
{
Q_OBJECT

public:
    explicit Darlehensrechner(QWidget *parent = 0);
    ~Darlehensrechner();

private slots:
void on_berechnenButton_clicked();

private:
Ui::Darlehensrechner *ui;
Darlehensgeber dg;
};

#endif // DARLEHENSRECHNER_H
@

And this is the cpp:
@#include "darlehensrechner.h"
#include "ui_darlehensrechner.h"

Darlehensrechner::Darlehensrechner(QWidget *parent) :
QMainWindow(parent),
ui(new Ui::Darlehensrechner),
dg()
{
ui->setupUi(this);
}

Darlehensrechner::~Darlehensrechner()
{
delete ui;
}

void Darlehensrechner::on_berechnenButton_clicked()
{
dg.takeLoan(ui->kreditEdit->text().toFloat(),
ui->ratenEdit->text().toFloat(),
ui->zinsEdit->text().toFloat());

ui->dauerLabel_2->setText(QString::number(dg.getAmountOfInstallments()));
ui->betragLabel_2->setText(QString::number(dg.getAmount()));

}

The code looks good. Most probably a issue in your Darlehensgeber implementation.
Infinite loop, etc. ?

Yes, was an infinite loop, thanks.
