It looks like the patch mentioned in http://<email address hidden>/msg708760.html that will allow the bug to be turned off has not yet been applied to 10.04.
I have a fully updated 10.04.3 LTS system, and bash reports version number 4.1.5(1)-release.
With this version of bash adding "set disable-signal-echo on" to inputrc does not fix the problem.
This bug is still present in "10.04.3 LTS"
