Bash previous-history command editing error

[GoogleCodeExporter]

Hi
What steps will reproduce the problem?
1. lets say I enter the command with a typo and instead of writing "echo 'test' 
I write:

user@linux:~$ echo 'tedt'

2. When I try to fix the typo by editing my last command (by pressing the up 
arrow on the keyboard), after deleting the 'd' (by pressing delete on the 
keyboard) and entering 's', the 'd' gets reinserted:

user@linux:~$ echo 'tesdt

3. and even if I fix the new error by deleting the d the output is still wrong:

user@linux:~$ echo 'test'
tesdt


What version of the product are you using? On what operating system?

I am using Conque version 2.3 with vim 7.2.330 on ubuntu 10.04


Please provide any additional information below.

The problem does not appear when using backspace instead of delete.
The same problem occurs when using ipython, or python.

Thanks :)
