After switching to call vundle#begin(), started getting VimEnter errors

[dpacmittal]

After I switched from vundle#rc() to vundle#begin(), I've started getting the following errors for NerdTree:

Error detected while processing VimEnter Auto commands for "*":

If I switch to rc() again, the error goes away. What am I doing wrong?

I think this issue is related #418. Some configuration clause should be out of the #begin() and #end() pair.
