An idea that doesn't solve the problem, but may provide an idea
for a workaround by changing the setting:

Maybe I'm the wrong person to say that, but I'm "doing it wrong"
all the time:

You are using \em, scoped by { ... } to emphasize text. The
recommended way is to use \textem{ ... }. If you try to use
the "non-fragile" LaTeX command instead of the "low level" TeX
macros, can you change the behaviour regarding the delimiters?

If you want to keep the \em macro, you could remove the scope
given by { and } and end the emphasized sequence by \rm, falling
back to "normal" roman typeface.

But as I said, I'm using {\em ...}, {\bf ...}, {\tt ...} and so on
on a regular basis. :-)
