 Replying to [comment:8 joseaneto]:
 > So the bug occurs in pdf files to which ImageMagick cannot apply "use-
 cropbox".[[Image()]]

 Yes, that seems to be the problem. Seems not in ImageMagick but in
 Ghostscript. This comment by @cranewest has some more info:
 https://core.trac.wordpress.org/ticket/48778#comment:12 and points to this
 (ancient) bug in GS 8.7:
 https://bugs.ghostscript.com/show_bug.cgi?id=690676. Perhaps see if your
 Ghostscript version is affected and try updating it if possible.

 Looking at what can be done in WP as a workaround, doesn't seem there are
 many options. Perhaps can try to set the option and load the .pdf file,
 and if it fails, remove the option and try to load again?
