After a couple of hours sleep I noticed, that I was wrong about that 
matter: The difference between <ALT> and <Ctrl> applies when /starting/
a new selection. When the <Ctrl> key is pressed while creating a new
mouse selection by Click&Drag, then the selection area has the last
saved ratio from the CustomCrop dialog. When starting this selection
with <ALT> key pressed, the selection is created with inverse ratio.
This matters when working with a whole bunch of pictures, that are
sometimes in portrait and sometimes in landscape format. 

When resizing an existing selection, the <Ctrl> and <ALT> keys behave 
likewise, assuming the selection may already have been altered from the 
CustomCrop dialog settings. So: No bug involved.
