Hmm, "jhead --purejpg" removes too much data (I still want to keep
date, exposure, etc.), and so does "exiftool -all=". But exiftool is a
really nice tool :)

Here is what I ended doing:

  exiftool -Subject= -Keywords= -Title= -Caption-Abstract= -Headline= **/*.[Jj][Pp][Gg]

(** is "recursive *" in zsh).

This cleaned every instance of the tags and titles in my photos, and led
me to discover a bug in Shotwell (http://redmine.yorba.org/issues/4264).
Hehe, I had to do some SQL by hand to restore missing titles from the
database :)

Thank you all for your help!

Regards,
