It is indeed a LaTeX issue!  And I have an answer too :).  Org mode
translates _underlined text_ to \underline{underlined text}, however if
you read the TeX.sx question referenced below you will see that it
doesn't support line breaks and the TeX community recommends \uline{..}
from the ulem package.

  <http://TeX.stackexchange.com/a/13382/4416>

For now you can write a filter to alter the LaTeX source[1]; for the
long haul you should start a separate thread asking to change the
defaults in Org mode.  However I'm not sure if that is desirable since
it introduces an extra LaTeX package dependency to handle corner cases.

Hope this helps,
