Check the profile template - it may be a matter of having something like:

<textarea ...>
<%user_interests%>
</textarea>

which would throw in one, possibly two (depending on the browser) extra lines. Instead, change it to:

<textarea ...><%user_interests%></textarea>

That will hopefully fix up the problem.
