As Torsten already stated, it's a bug.

First bad commit:

commit b357d2084d1ae252a890e92019e62aa8ccbfdafc
Author: Dan Eble <address@hidden>
Date:   Wed May 27 20:56:37 2015 -0400

    Issue 4423: eliminate part combiner's array of context handles (3/4)

    Use NullVoice instead of Devnull for the "null" context.  This makes
    all outlets a kind of Voice.


Introduced in 2.19.22
