Game crashing item

My version is 0.9 stable
I’m in SDL, no tileset, nothin’
I’m on Windows 7

So, I don’t know how I got it, I just stack all of my bullets in once place (sometimes guns) and BLAM.

It’s very, very annoying. Whenever I’m scrolling through the pages I accidentally scroll over it and my game crashes.
I’ve tried too move other items, but, It won’t change at all.
