Indeed that is the culprit.

The CDPATH behaviour seems verry odd. Doesn't that also break postint
scripts for you? Debconf uses stdin/out to communicate with the
postinst script and if that does a cd then debconf will give an error
and everything breaks. Also any shell script you call that does a
relative cd might get the totaly wrong directory. Seems like setting
CDPATH for non-interactive shell should randomly break things all over
the place.

I would suggest only setting it for interactive shells. E.g. set it in
~/.bashrc and not ~/.profile and do not export it.
