While bonemealing a Palm Seed from the Dynamic Trees mod for Biomes O' Plenty, I got a crash with this mod when it tried to generate a sprite for the Palm Leaves.
Crash Report

I had a very similar crash with Dynamic Trees. I only noticed it after installing Dynamic Trees - Neapolitan mod, when I went to a jungle (where Neapolitan's banana plants spawn) and immediately crashed.
