Cursor in terminal behaves badly with special characters present

Bug description:
Binary package hint: xfce4-terminal
Both xfce4-terminal and gnome-terminal are affected, but not the text-
only terminals (alt+f1, f2 etc.). So probably the package hint is
wrong...
Description:
With special characters present before the $ sign, when going back to the
previous line (backspace or cursor keys), the cursor jumps to the left too far
(one character per special character).
How to reproduce (cf. always my attachment):
1. Open the terminal (in X, not the real text-only screens)
2. Create a folder with special characters in it, e.g. with german special
characters: $ mkdir abcäöü
3. Go to the special character folder. $ cd abcäöü
4. Type some rubbish until you reach the end of the screen (in my attached
example: "abcdefghijklmnopqrst". As soon as you have filled up the last column
(the "t" in my case), the cursor jumps correctly to the next line.
5. Hit backspace or the left cursor once. Backspace eats 2 characters instead
of one if one special character is present (3 if there are 2; 4 if there are 3
etc.).
6. Hit return. Bash says it does not know the rubbish that you've actually
typed (not the rubbish that was displayed). So obviously this is a display
problem, not an input problem.
Instead of step 4, you can also type some new rubbish. It will be
inserted into the old rubbish exactly the way you type it, but it
won't display correctly. It's like a blind flight: As long as you know
exactly where you are, you'll land on the airport. But never try to
tell your position from what you see...
The bug is most probably not a duplicate of Bug #238055 or Bug #88504.
The symptoms described there don't match ours here.
Xubuntu 9.04, up to date as of July 15 2009.

WORKAROUND:
1. The correct text can be displayed by hitting the up and then the down
cursor button.
2. The bug is triggered by special characters in what comes before the $
sign. If those special
characters are removed from the prompt, the terminal acts correctly.
