apacite problems

[jgi...@netmar.com]

I've attempted to install and use apa document class with apacite, but
something isn't right.

All my citations come up (?,?). The references section gets produced
correctly, however.

If I run latex,bibtex,latex,latex... latex complains on the first two
runs about Undefined citations, then on the third run says:

Runaway argument?
>{\typeout {No file \jobname .bbl.}}\else \def \reserved@a {\@iffileonpath \ETC
.
! Paragraph ended before \@@cite was complete.
<to be read again>

Bibtex seems to run ok and produces the bbl and aux files.

Here's the latex version information:
This is e-TeX, Version 3.14159-2.1 (Web2C 7.4.5)

Here's the aux file:
\relax
\bibstyle{apacite}
\citation{Giglio2001}

Here's my latex file:
\documentclass[english,man]{apa}
\usepackage[T1]{fontenc}
\usepackage[latin1]{inputenc}

\makeatletter
\author{Author} % hack around some bugs in apa.cls
\affiliation{Affiliation} % hack around some bugs in apa.cls

\usepackage{babel}
\makeatother
\begin{document}
\cite{Giglio2001}

\bibliography{/home/jgiglio/personal/capella/TS3004/testbib}

\end{document}

Here's my .bib file

@Article{Giglio2001,
Author = {Giglio, J},
Title = {Doing things with stuff, a guide.},
Journal = {Journal of the Gigs},
month = {1 } # dec,
year = 2005
}

Hmm, Apparently using natbib fixes this for some reason:

\usepackage[authoryear]{natbib}

Well that solves my problem I guess, I'm still confused on how all this
interacts though (I'm a LaTeX newb).
