AFAIK it is not known.  I am able to reproduce it (Linux, HEAD code), so I
suggest you file an ITS.  With respect to a workaround, it is not clear
what's the purpose of the operation you're trying to accomplish.  In
general, a modrdn on the empty DN should be meaningless (although it
should not crash the server).
