I applied word-wrap: break-word to twitter bootstrap dropdown-nemu, but it didn't work. Here's the JSFiddle.
I tried a simplified sample and it worked:
<ul style="width: 60px">
<li>
<a style="word-wrap: break-word">fdsssssssssssssssssssssssssdfdsfsdfsdf</a>
</li>
</ul>
It was because of white-space: nowrap property with link.. add this line:
<li><a href="#" style="word-wrap: break-word; white-space: normal;">sometextsometextsometextsometextsometext</a></li>
..or use full fiddle here: http://jsfiddle.net/Ex5fA/45/ (you had also typos with your .dropdown-menu selector.. it was typed .dorpdown-nenu ;)
