Hi,
Nobody replied to my question, but finally I solved it myself. To be complete, 
I will post the solution here.
I found a statement somewhere that USB removable disk technology in 
combination with SD cards contains code which is patented. When I switch the 
camera back to camera mode, the usb removable disk technology is not 
activated and the errors do not occur.
The solution is to use gPhoto and the frontend gtkam which is able to get the 
photos off the camera.
