Hi TeX Hackers,

I've run into yet another problem and it's driving me insane. I have
the following in my thesis:

\citet{AmorEtAl:2005:MLSUD3aaCSPR} find ``Debian [to be] one of the
largest software systems in the world, probably the largest.''

When I compile with teTeX, everything works, I then run BibTeX and it
reports no errors, I then run teTeX again and it works but still
reports unresolved references, so I run it a third time to get:

  ! Argument of \@citex has an extra }.
  <inserted text> 
  l.403 \cite{AmorEtAl:2005:MLSUD3aaCSPR}
                                          find ``\D\ [to be] one of the

I just can't make sense of it, don't know what \@citex is, and
cannot for the life of me see an extra } anywhere.


This is the BibTeX entry (I am using UTF-8, which works okay everywhere else):

  author = {Juan-José Amor-Iglesias and Jesús M. González-Barahona and Gregorio
  Robles-Martínez and Israel Herráiz-Tabernero},
  title = {Measuring Libre Software Using {D}ebian 3.1 (Sarge) as a Case Study:
  Preliminary Results},
  journal = {UPGRADE: the European Journal for the Informatics Professional},
  year = {2005},
  volume = {6},
  pages = {13--6},
  number = {3},
  month = {June}

and this is the .bbl entry:

\bibitem[Amor-Iglesias et~al.(2005{\natexlab{a}})Amor-Iglesias,
  González-Barahona, Robles-Martínez, and Herráiz-Tabernero]{A}
