sbcl + linedit

I posted to the linedit dev list about a couple of problems I'm having, i'm not sure if it's a bug or misconfiguration. Not had a response yet, though it was only yesterday morning that I posted!

It seems to hang if I press CTRL-arrow (ie to move the cursor at word
boundaries instead of a char at a time). CTRL-C does not get out of this
hung state and I have to open another terminal and kill sbcl from there.

Home and End keys do not work and 'Unknown command "M-O".' is
displayed along with a H or F as user-input.

I'm running sbcl-1.0.18-debian in Debian Lenny for the AMD64 platform.

Any ideas?

Thanks,
James.

OK, I've taken the 'trouble' of looking into the source for linedit, in particular the command-keys.lisp file, and have seen that the functions i was looking for are implemented just not using the keys i expected. It would be interesting to know why CTRL-any-arrow-direction-key causes a hang tho.
