    Description

      The DSEngine crashes very often if the camera (QCamera) stops. It crashes in dscamerasession.cpp, line 537 (DSCameraSession::onFrameAvailable()). The 'buffer' passed to the slot is invalid and it failes on QByteArray inicialization. I'm sending a screenshot from QT Creator in debugger mode.

      It is suspicious the DSCameraSession is in state of LoadedStatus while it is receiving new frame (slot onFrameAvailable()).
