        Nope it's not.  It's floating.  IIRC, the datasheet indicates that
this
        doesn't matter.  Been a while, so I'll go verify that.  But either
way, I've
        never had to do this.  Is this a known bug/prob/etc?

        Cheers,

Yes, the LVP pin should always be pulled low when programming.  LVP enabled
PICs come set for LVP operation from the factory, if this line floats high
enough the PIC will enter the programming state at inoportune moments.  Some
people have never encountered this, but I have definately had it happen to
me.
