I've just seen the same problem, on a newly-installed RedHat 5.1 Linux
system with the zsh-3.0.5-2 RPM.  The /etc/zshenv file contains

	if [[ `id -u` -eq 0 ]]
	then
	    ...
	fi

and zsh randomly fails to capture the output of `id -u`.  It seems to
occur only when I rapidly exit and immediately log back in; if I wait
any longer than it takes to retype my login and password as fast as I
can, the problem disappears or becomes much more sporadic.

I ended up replacing `id -u` with $EUID and haven't seen any further
problems.  I'd assumed it was something about the "id" program.

I suspect zsh is getting some kind of a signal -- perhaps SIGWINCH? --
which is interrupting the read on the command substitution.
