In a konsole terminal resized to

# echo $LINES
25
# fdisk --version
fdisk from util-linux 2.26.2

Yes, the main menu scrolls off the top do the topmost line is:

n   add a new partition

but that is not a big problem in konsole because I can scroll back the 
buffer.  The l command lists the partition types and the topmost line of 
the screen is entry number 44.

If it's meaningful, for konsole, I do not use a LANG or any LC_* 
variables and the TERM variable is xterm.

The difficult problem is in busybox where there is no scroll back 
capability.

The problem should be relatively easy to reproduce.  Get a copy of 
debian-8.1.0-amd64-DVD-1.iso and boot it either to HW or in a virtual 
system (I'm using qemu).  Follow the prompts and drop to a terminal and 
then run fdisk.
