- A comment on [StackOverflow question](https://stackoverflow.com/questions/53560755/ghostscript-9-26-update-breaks-imagick-readimage-for-multipage-pdf) from yesterday suggests it might be a bug with the `pngalpha` device in Ghostscript and [links to an upstream bug](https://bugs.ghostscript.com/show_bug.cgi?id=699815)
- I think we need to wait for a fix from Ubuntu
- For what it's worth, I get the same error on my local Arch Linux environment with Ghostscript 9.26:
```
$ gs -q -dQUIET -dSAFER -dBATCH -dNOPAUSE -dNOPROMPT -dMaxBitmap=500000000 -dAlignToPixels=0 -dGridFitTT=2 -sDEVICE=pngalpha -dTextAlphaBits=4 -dGraphicsAlphaBits=4 -r72x72 -dFirstPage=1 -dLastPage=1 -sOutputFile=/tmp/out%d -f/home/aorth/Desktop/Food\ safety\ Kenya\ fruits.pdf
DEBUG: FC_WEIGHT didn't match
zsh: segmentation fault (core dumped) gs -q -dQUIET -dSAFER -dBATCH -dNOPAUSE -dNOPROMPT -dMaxBitmap=500000000
```
- When I replace the `pngalpha` device with `png16m` as suggested in the StackOverflow comments it works:
```
$ gs -q -dQUIET -dSAFER -dBATCH -dNOPAUSE -dNOPROMPT -dMaxBitmap=500000000 -dAlignToPixels=0 -dGridFitTT=2 -sDEVICE=png16m -dTextAlphaBits=4 -dGraphicsAlphaBits=4 -r72x72 -dFirstPage=1 -dLastPage=1 -sOutputFile=/tmp/out%d -f/home/aorth/Desktop/Food\ safety\ Kenya\ fruits.pdf
