I nailed it down. Here is a small reproduction case:

1) Install the pnambic plugin

2) Open attached document

3) Do *not* insert _anything_ before the pnambic session, not even a
   blank paragraph.

4) Go directly to the first input field of the pnambic session, press
   the enter key.

5) Give this as input:

[02]command:(define p (position-new))(position-set p '(0 0 4 0 1 0))(set! p 
#f)[05]

6) Wait a fraction of a second (this is necessary to separate the
   startup input from the answer to the request).

7) Give this as input:

[02]command:(set! p (position-new))(position-set p '(0 0 4 0 1 0))[05]
