Hi Jon,
I don't know if this matters or not, but these are the changes we make 
to the SL4 thunderbird source rpm in order for it to compile and work on 
SL3.

-#sw start
-sed -i 's/enable-pango/disable-pango/' .mozconfig
-#sw end

So, you see that we only disable pango when it's being compiled.  But 
that doesn't look like the problem you are having.

Are you sure that the SL3 machine has it's timezone and glibc up to date?

Also, does he have the new seamonkey that just came out last week.  The 
one before it broke evolution, gaim, and potentionally other things, 
maybe by some freak chance, it broke lightning as well.
