Did you also upgrade zsh at the same time?  You should have been having
troubles with zsh much earlier since my change to the *env() function
went in early July.  :)  zsh 4.3.4 has a bug where it was mixing calls
to *env() functions with direct manipulation of environ.  The CVS
version of zsh is fixed.  I created PR ports/115094[1] to patch it in
the ports tree about a month ago.  *nudging sergei*  :)

There should be something besides ^[[4~ printed, but the internal
function __merge_environ() has been presented with an environ it could
not handle.
