Bob, I'm not sure I understand the problem, but I'm guessing you inserted a character like → into the text, while not in math mode. If so, you could try to circumvent the problem by going to Document > Settings > Fonts and changing the template's Roman font from "Palatino" to "Default".
I don't see the same pdflatex crash as you, but LyX displays a latex error message if I try to use Palatino font with that "\textrightarrow" character. So I can't be sure if this helps you. Could it be that your TeX installation is out of date? It may be worth thinking about how LyX can keep track of pdflatex processes it has spawned, so that it can "kill -9" crashed processes when the user exits LyX (after warning about it). I don't think that anything like that has been implemented at this point. And of course that wouldn't help fix the root cause of your problem.
