History (readline?) problem with color prompt

Binary package hint: gnome-terminal

I think I've hit a readline problem (if Terminal uses it) that makes long lines and color prompts very hard to use at the same time. This never happened before Feisty.

version: gnome-terminal 2.18.0-0ubuntu1

To reproduce:

1. put up a simple color prompt, like:
    PS1='work:\e[0;31m\w\e[m # '
2. type or paste a long line, like:
    echo '123456789123456789123456789123456789'
3. don't execute it, but instead press Home to position the cursor on the beginning of the line
4. notice the cursor is *not* at the beginning!
5. press End to position the cursor at the end of the line
6. the cursor is now too far on the right!
7. try to delete all the characters (Backspace) - you won't be able to!
8. put up a non-colored prompt, like:
    PS1='\w # '
9. try to repeat the steps above - it works fine now.

This bug does not only break Home and End in the terminal; it also manifests itself when revoking long lines from history (UP key).
