Have you tried installing optifine? I used to get renderer crashes a lot until I started using that.
But I fear that your inventory must be cleared to fix this otherwise (I take it there's no easy way to remove one single inventory item out of a players data file ?)
Have you tried scrolling like crazy while logging in so perhaps it at least is able to send one message causing the map to not be your currently selected item
