They are not the same; the stack tracebacks are very different. The bug
in that launchpad report was fixed with bash-4.3 patch 9 and had to do with
history expansion. This bug has to do with the behavior of readline's
revert-all-at-newline option.

There is a fix for this in the devel git branch, but there has not been any
official patch released yet. It was just reported a couple of weeks ago
while I was on vacation.
I have attached a patch originally from Jared Yanovich that should fix the
problem.
