      <br>
      what exactly did you load?<br>
      <br>
      The patch from Anselm is from 2012-09-28.<br>
      <br>
      python-2.7.2-stackless.msi is still from 2011-12-12.<br>
      As far as I can see, all installers and binary packages are older
      than the patch.<br>
      <br>
      Eek - you would need to build from source I think.<br>
      <br>
      ciao - chris<br>

                        <div>Hi Lars,<br>
                          <br>
                          this is good information!<br>
                          Since you don't get crashes from using
                          stackless features, it is<br>
                          pretty clear that the problems must come from
                          things that<br>
                          I changed to support stackless features.<br>
                          <br>
                          Good to know.<br>
                          Still, it would be nice if we had something
                          more deterministic to<br>
                          cause a crash, especially a crash that occurs
                          without manual<br>
                          interaction...<br>
                          <br>
                          I think to have a closer look into PySide
                          itself, to see if it uses<br>
                          structures which are not officially public.<br>
                          <br>
                          One thing would be interesting but involves

                          Can you install PyQt instead and try the same?<br>
