Printing stops at the slide using LaTeX

Hi, I found that the printing will stop at the slide using the package slideshow-latex. For example, if I use the LaTeX function at slide 7 while I have 10 slides, then slideshow can only print the first 7 slides.

The terminal gives the following info:

James:~ ► slideshow --print my_slideshow.rkt

Reproduce the failure with slideshow --print my_slideshow.rkt using a LaTeX slide. Start with slideshow/start.rkt and slideshow/latex/latex2bitmap.rkt, especially the reported locations around lines 171 and 198. Done means printing continues past the LaTeX slide and includes all remaining slides.
