zsh 4.3.10 segfaults, bindkey -d related

[George Cox <gjvc@xxxxxxxx>]

Hi,

I have recently been able to reliably crash zsh 4.3.10 (built via
FreeBSD ports on FreeBSD 8.0-STABLE)  Below is a stack dump I've been
able to collect from the core files.  I've been able to replicate the
first one quite easily.  I first enter an incorrect path, and press
<TAB> for completion, then press any key to continue with input and
boom.

[gjvc@beaujolais] > cd etc/zhs_
<TAB>

[gjvc@beaujolais] > cd etc/zhs/_
corrections (errors: 1)
zsh/      zsh.old/
original:
etc/zhs
<ANY KEY> 

and it crashes

I've tracked this down to the presence of 

    bindkey -d  # delete all existing keymaps and reset to the default state

in my zsh startup files -- if I comment out 'bindkey -d', zsh doesn't
crash.  Hope this helps someone!

best;
