Just a quick guess:

Deri's recent changes mean that ImageMagick/PerlMagick might be called
from either or both of "pdfpic.tmac", so at formatting time, or at
_rendering_ time by the output driver.

The `-z` flag prevents the output driver from even running, because the
troff output it needs to read is never created in the first place.
