title: Can't build, qmake.exe crashes in Qt Creator
body: <p>I'm using Qt Creator on Windows XP SP3. I want to develop C++ desktop applications.</p>
  
  <p>I made a new project. Everytime I click build, it appears a window which says:</p>
  
  <blockquote>
    <p>qmake.exe has encountered a problem and needs to close. We are sorry for the inconvenience.</p>
  </blockquote>
  
  <p>In Qt Creator, something similar to this appears:</p>
  
  <pre><code>20:36:55: Running build steps for project yyy...
  20:36:55: Starting: "d:\qtsdk\desktop\qt\4.8.1\mingw\bin\qmake.exe" D:\...\yyy.pro -r -spec win32-g++ "CONFIG+=declarative_debug"
  20:38:00: The process "d:\qtsdk\desktop\qt\4.8.1\mingw\bin\qmake.exe" crashed.
  Error while building project yyy (target: Desktop)
  When executing build step 'qmake'
  </code></pre>
  
  <p>I can't build, I have reinstalled the software but it keeps giving the same error.</p>
  
  <p>Can you give me any idea of what is happening?</p>
