Misplaced <div> in viewcode html output since Sphinx 1.7.0

[jfbu]

Image shows it:

there is an extra line above the final one of the procedure, and the html source (in _build/html/_modules/foo.html) looks like this

<div class="viewcode-block" id="pgcd"><a class="viewcode-back" href="../index.html#foo.pgcd">[docs]</a><span class="k">def</span> <span class="nf">pgcd</span><span class="p">(</span><span class="n">a</span><span class="p">,</span> <span class="n">b</span><span class="p">):</span>
    <span class="sd">&quot;&quot;&quot;Calcule le PGCD par l&#39;algorithme d&#39;Euclide.</span>
<span class="sd">    &quot;&quot;&quot;</span>
    <span class="n">a</span><span class="p">,</span> <span class="n">b</span> <span class="o">=</span> <span class="nb">abs</span><span class="p">(</span><span class="n">a</span><span class="p">),</span> <span class="nb">abs</span><span class="p">(</span><span class="n">b</span><span class="p">)</span>
    <span class="k">while</span> <span class="n">b</span> <span class="o">&gt;</span> <span class="mi">0</span><span class="p">:</span>
        <span class="n">a</span><span class="p">,</span> <span class="n">b</span> <span class="o">=</span> <span class="n">b</span><span class="p">,</span> <span class="n">a</span> <span class="o">%</span> <span class="n">b</span></div>
    <span class="k">return</span> <span class="n">a</span>

the closing </div> is mis-placed (not at end of last line but at end of previous one).

This does not happen with Sphinx 1.6.6 but happens with Sphinx 1.7.0 and 1.7.1

I am attaching
misplaceddiv.zip
which one needs to compile with make html.
