privileged instruction

after updating my project to qt 5.1.1, whenever i close the application, i'm presented with this error. i've tried uninstalling and reinstalling all qt related things, using both mingw and msvc packaged builds from the qt site. stepping through things, the exception is happening after the main loop ends. i've really got no idea how to debug this.

this was being caused by deleting a pointer to a custom QTextCodec object. no crashes occurred while the application was running, only upon exit.
