    Hi, maybe you already checked this, but if you have any big wheels
    like a QFileDialog declared static, their ctors most likely will run
    before main(), i.e. some COM/networking activity could occur before
    main() kicks in.<br>

      <p>As I said, I now have doubts it comes from COM threading...</p>
      <p>I have built a small app with nothing inside, with the same
        .pro file exactly (qt modules, libs, etc, in the same order).
        The only difference is HEADERS and SOURCES of course, main.cpp
        being the same at least until it crashes. No problem in this
        small app (running in the same directory).</p>
      <p>Again for those who missed it:</p>
      <p>main.cpp:</p>
      <pre><span>    </span><span>QNetworkAccessManager</span><span> </span>*<span>inet</span><span> </span>=<span> </span><span>new</span><span> </span><span>QNetworkAccessManager</span>();</pre>
      <pre><span>    </span><span>delete</span><span> </span><span>inet</span>;</pre>
      <pre><span>    </span><span>QApplication</span><span> </span><span>app</span>(<span>argc</span>,<span> </span><span>argv</span>);</pre>
      <pre>this works.</pre>
      <pre><span>   </span><span>QApplication</span><span> </span><span>app</span>(<span>argc</span>,<span> </span><span>argv</span>);</pre>
      <pre>   <span></span><span>QNetworkAccessManager</span><span> </span>*<span>inet</span><span> </span>=<span> </span><span>new</span><span> </span><span>QNetworkAccessManager</span>();</pre>
      <pre><span>    </span><span>delete</span><span> </span><span>inet</span>;</pre>
      <pre><span></span>this crashes on new in our app, not in a sample without HEADERS and SOURCES.

I cannot understand that, certainly there is something obvious I am missing.
