r60 Crash when closing inactive layer tab

I've been experimenting with Layout switching and WebStorage and got a bug that the UI asked that I report.

--------------------------------------------------------------------

ENVIRONMENT:

--------------------------------------------------------------------

Construct2 r60

MacBook Pro 64bit running Windows Vista Parallels Virtual Desktop VM

--------------------------------------------------------------------

ZIPPED PROJECT:

--------------------------------------------------------------------

dl.dropbox.com/u/4432971/game2.zip

--------------------------------------------------------------------

STEPS TO REPRODUCE:

--------------------------------------------------------------------

1) Open Layout 1, 2 & Event Sheet 1

2) With Layout 1 active, Select the Event Sheet 1

3) Close Layout 2 via the tab

4) At this point I got the below exception. Although I tried to continue, the app crashed.

--------------------------------------------------------------------

THE EXCEPTION DETAILS:

--------------------------------------------------------------------

Construct 2 Check failure

---------------------------

Check failure! This is probably a bug:

Object has no animations

Condition: !anims.empty()

File: Projects\ObjectType.cpp

Line: 911

Function: class ObjectTexture &__cdecl ObjectType::GetFirstAnimationFrame(void)

Build: release 60 (64-bit) checked

Component: Construct 2 IDE

(Last Win32 error: 0)

Hi, I can't reproduce this on Windows 7. I've tried:

1. Open the .capx. Tabs for Layout 1, Layout 2 and Event sheet 1 are open, and Event sheet 1 is displaying.

2. Click the Layout 1 tab.

3. Click the Event sheet 1 tab.

4. Middle click Layout 2 tab to close it.

I don't see any error. Am I doing something different to you?

I cannot get the error to occur again either. I'm not sure if the stack trace I sent helps but I thoughtI should at least contact you.
