i had that problem a few min ago , and while i forgot what exactly fixed it the things i did was:

1) comment out the registering of a block i had commented the creation out of

2) add .setUnlocalizedName("string"); to my item

 

i think the top fixed mine but the bottom one came up next with some name error

 

the texture system isnt too bad really for what i'm doing ( as far as i can tell ) but essentialy in your mod folder you need a textures folder with items and blocks folders in that

 

[edit]

 

this is the function that ( for the workbench) will set the icons to vars needed so it can render, i think items are the same function. later in the get block texture function it returns those set variables

@SideOnly(Side.CLIENT)
    public void func_94332_a(IconRegister par1IconRegister)
    {
        this.field_94336_cN = par1IconRegister.func_94245_a("workbench_side");
        this.field_94385_a = par1IconRegister.func_94245_a("workbench_top");
        this.field_94384_b = par1IconRegister.func_94245_a("workbench_front");
    }
