title: QCoreApplication::notifyInternal Segmentation fault
body: <p>Hello I'm developing a shared library  in c++ and I'm testing it using a QT interface. Everything seemed ok, but suddenly the application crashed and give me the following core dump:</p>
  
  <blockquote>

  <p>I'm running in ubuntu 10.10 installed in a SD card, and I'm using QT 4.7.0. In Windows the application works ok, and in Linux too, until the application crashed at a random time. I don't know if a QT bug with ubuntu or something like that, because I have read in internet, applications with similar core dump.</p>
  
  <p>Thanks!</p>
