title: Strange error while using Pycharm to debug PyQt gui
body: <p>I've been using PyCharm to debug my gui in PyQt. This has been really successful thus far, until I've run into a strange error in trying to debug my gui just now. I've set a breakpoint at the beginning of the script as well as at various points but the program does not have a chance to get to this point. I've also tried removing all the breakpoints and running the debug but get the same result. The full traceback is:</p>

  <p>Does anyone know what is causing this error and how it can be resolved? When I run the code normally (without debugging) I do not run into any of these errors.</p>
