The ultimate cause of this particular problem was permissions on the
"functions" directories not being to zsh's liking (ie: having write
permission for group or other).  This was a build error on my part for
4.3.11-1, which was corrected in 4.3.11-2.
(Make sure you have installed 4.3.11-2, btw :-)

With the permissions wrong, compinit fails to load any of the completion
functions and ends up creating a very, very abbreviated .zcompdump file
(less than 1k in size, versus > 30k size).
You can tell this by looking at the .zcompdump and if it things like
_comps() are mostly empty, then you are hitting the problem.

Verify that you .zcompdump has move that a few functions in it and verify
the permissions on all directories under /usr/share/zsh/4.3.11 are 755
(rwxr-xr-x) and that all files under those directories are 644
(rw-r--r--).

This is, of course, assuming that this is the problem you are
experiencing, rather than some new, unidentified, problem :-)

If you've checked the above, then the next thing is to send me your
.zshrc (or at least those parts of if you feel exhibit the problem).
