Titanium SDK 3.2.0 crashing randomly when opening new window in NavigationWindow

Question

It's happening very randomly, sometimes on opening first window, sometimes after 9 or more.

I've got this bug after upgrading from Titanium 3.1 to 3.2 where NavigationGroup was replaced with NavigationWindow.

One of below stacktraces shows up:

It's hard to tell without seeing the JS code that causes the crash, but it seems as if you are trying to access and object outside the array or that in null: -[__NSArrayM objectAtIndex:]: index 4 beyond bounds [0 .. 1]

Try posting the code where you recognize the crash happens.

The biggest problem is that I have no idea in which part of the code is triggering this issue. I was removing smaller and bigger parts of it and it's still there. Also whole process is very time consuming, because it's hard to trigger this bug very easily. – daniula Jan 31 '14 at 11:29
Does it happen right when you open the app, or after you perform some operations in it? I would try to write to console / log sequential numbers in my code and see what the last number that is shown - that's how I usually know where my app crashes and then try to narrow it down even more. – developer82 Jan 31 '14 at 13:33
It's happening when I'm adding new windows to NavigationWindow. I was trying trick with with console.logs() and during crash none of them was showing up. I started suspecting that this issue is going somewhere behind. – daniula Jan 31 '14 at 13:36
