Tested with forge 1291 and also newer, downgraded mod to 2.75 and 2.76, didnt help.

Do you know what kind of recipes are in it?

The problem is most likely that you were using recipes that have changed (due to a mod updating) or the resulting item no longer is valid. I will make the crafter more robust so that it no longer crashes in this situation. In the mean time I recommend reverting your updates and clearing the crafters for possible recipes that may be changed in the mods you were updating.
