It seems to be pretty much 100% crash for me no matter what file I open. If I mouse over a slot (pretty much all my slots have multiple attachments), it crashes. It's making it nearly impossible to work as you can imagine.

The spine.log doesn't have anything interesting in it.

I've attached the text from the error pop up.

I have created a new project that crashes.

If you try to drag an image (explosioncloud0) onto the slot named "test", it will crash (on my machine).

The steps were

1. Create new project
2. Add a slot named "test" under the root bone
3. Drag explosioncloud0.png to test

Also, the application is crashing at many other times like when I save (15%) or when I edit an animation name (5%). It is possible that I am mousing over slots or causing slots to be selected to cause these as well. I have submitted all the error pop ups. I wouldn't be surprised if I've already submitted 50 in the last 2 hours.

Given that you couldn't reproduce it. I tried the classic "restart my computer" solution and it seems to be working fine now. Why didn't I think of that earlier?
