:-) You'd be a little less shocked if you worked with macros in C :-)

You have a command in foo.tex that can't be nested further. I think they're
called "fragile commands", although we're getting past my LaTeX expertise at
this point. You already found the solution -- surround with
makeatletter/makeatother.
What surprises me is that it's dependent on LyX version. If the LyX file is
called bar.lyx, I'd like to see you do the following:
lyx-1.5.4 -e latex bar.lyx
mv bar.tex bar-1.5.4.tex
lyx-1.6.2 -e latex bar.lyx
mv bar.tex bar-1.6.2.tex
diff bar-1.5.4.tex bar-1.6.2.tex
Then run latex on both tex files and see if one errors out while the other
doesn't. Exploit the differences.
