ImageMagick maybe broken by libgs9 upgrade

[Emily]

I use ImageMagick to convert and crop shipping labels from PDFs generated by Ebay.  On 6/8, this command worked:

$ convert -density 300 -crop 1500x1200 label.pdf label.png
Aborted (core dumped)


The command still runs on PDFs that were not generated by Ebay, but I get the same error on old Ebay PDF files (from 6/8 and earlier) that previously converted and cropped without problems.


This is in my /var/log/setup.log:

2020/06/09 19:52:15   29 install libgs9                9.52-2
2020/06/09 19:52:15   30   erase libgs9                9.27-2


Cropping in a separate step after converting to PNG still works:

$ convert -density 300 label.pdf temp.png
$ convert -crop 1500x1200 temp.png label.png


But in case other ImageMagick functionality is also broken, this isn't a permanent solution.  I tried to downgrade libgs9, but 9.27 is no longer an option in setup, even after I added another mirror.

Thanks for your help!
