--- Comment #11 from walch.martin at web.de ---
I can reproduce it in Konsole 2.12.3 (KDE 4.12.3) with bash 4.2.45(1) as
described. The -n switch of echo is important to suppress the trailing newline.

Maybe it helps when I describe it in more detail:
- run Konsole with bash in it
- the exact prompt does not seem to matter, but lets set it to a constant
string:

PS1="P: "

- now execute the echo command

echo -n foobar

The last two lines of the Konsole window (not necessarily at the bottom of the
window) should look like this:

P: echo -n foobar
foobarP: 

As you can see, the prompt is printed immediately after foobar. When now
resizing the window in a way that adds a line to the running bash, the last
line is deleted and the prompt is reprinted. Now the two lines from above have
changed to:

P: echo -n foobar
P:
