While executing a crop with the ImageMagick convert and the picture is bigger on either width or height but smaller at the other parameter, the convert command is not able to process correctly.
It results in 1 negative and 1 positive Offset for the Crop parameter.
To Solve the Problem you have to make sure both offsets for the Crop Parameter are either positive or negative.

You can achive this by extending the if queries at \t3lib\class.t3lib_stdgraphic.php line 2274-2284 like this:

// Cropscaling:
if ($data['crs']) {
    if (!$data['origW'] || ($data['origW']>$data[0] && $data['origH']<$data[1])) {
        $data['origW'] = $data[0];
    }
    if (!$data['origH'] || ($data['origW']<$data[0] && $data['origH']>$data[1])) {
        $data['origH'] = $data[1];
    }
    $offsetX = intval(($data[0] - $data['origW']) * ($data['cropH'] + 100) / 200);
    $offsetY = intval(($data[1] - $data['origH']) * ($data['cropV'] + 100) / 200);
    $params .= ' -crop ' . $data['origW'] . 'x' . $data['origH'] . '+' . $offsetX . '+' . $offsetY . ' ';
}
