  • This crash seems to be very random Nathan, especially as the PyInit_aud function is only executed when the GE is started, so while running it's never called again. Moguri for example gets the following backtrace: http://www.pasteall.org/15305

    And I get this one:

    Mine looks like the game loop is still running although the window is destroyed, so that's the real bug I guess (at least one of them if there are more). You might consider reassigning, as this really doesn't seem to be related to my code. :)

  • fixed r33399,
    detect closing window and exit as if Esc was pressed.
