You might want to consider upgrading.

Odd; I've never seen this.  You may want to try the experimental
bash 3.1 to see if the problem has been addressed by upstream
fixes (bash 3.1/readline 5.1 added new features that make
bindings track terminal settings better, but ^A and ^E aren't
usually set to terminal control characters).  If you could come
up with something a little more definitive to reproducing this,
it would be a great help in the debugging effort.

The readline command re-read-init-file (by default, bound to
the sequence Ctrl-x Ctrl-r) will restore the bindings in your
~/.inputrc without having to close and reopen your terminal.
