Wrapped Box crashes client

[Antares]

When opening the item Wrapped Box (12023), the client crashes. Aside from it's id, everything is the same as Gift box. It gives IG_GiftBoxChina item. I can see it's name and sprite and everything just fine, but when I open it boom crash. Why? Even the item it gives is okay. No problem with sprites or names. I have 2012-04-10 client.

How can I make this work?

[Promise]

Try to remove all the items inside the box and replace them for an apple, so you can check if the crash comes from the script or it comes from some item of this itemgroup.

After relogging I had no problem viewing the items in my inventory. It's more like there would be some kind of effect when using the item that crashes the client, but I can't find anything in the item's script.

Everyone crashes on screen when opening the box, so it's very much likely that there is some effect. How can I remove item use effects?
