I have a WebView in a NSWindow and when I close the window and open it again the app crashes ;(

The window is called by a menu item button.

Here is the output:

    mainFrame is a method on WebView

    so

    points to your WebView being released either by you explicitly or implicitly by the OS when the window is shut. You are hitting a dead pointer.

    Not sure how you are setting up your window but you are probably assuming that the original WebView is still a valid object at a reopen.

    Have a look in that direction.
