- I inspected the troublesome PDF using [jhove](http://jhove.openpreservation.org/) and noticed that it is using `ISO PDF/A-1, Level B` and the other one doesn't list a profile, though I don't think this is relevant
- I found another item that fails when generating a thumbnail ([10568/98391](https://hdl.handle.net/10568/98391), DSpace complains:

- And on my Arch Linux environment ImageMagick's `convert` also segfaults:
```
$ convert bnfb_biofortification\ Module_Participants\ Guide\ 2018.pdf\[0\] -thumbnail x600 -flatten bnfb_biofortification\ Module_Participants\ Guide\ 2018.pdf.jpg
zsh: abort (core dumped) convert bnfb_biofortification\ Module_Participants\ Guide\ 2018.pdf\[0\] x60
```
- But GraphicsMagick's `convert` works:
```
$ gm convert bnfb_biofortification\ Module_Participants\ Guide\ 2018.pdf\[0\] -thumbnail x600 -flatten bnfb_biofortification\ Module_Participants\ Guide\ 2018.pdf.jpg
```
- So far the only thing that stands out is that the two files that don't work were created with Microsoft Office 2016:
```
$ pdfinfo bnfb_biofortification\ Module_Participants\ Guide\ 2018.pdf | grep -E '^(Creator|Producer)'
Creator: Microsoft® Word 2016
Producer: Microsoft® Word 2016
$ pdfinfo Food\ safety\ Kenya\ fruits.pdf | grep -E '^(Creator|Producer)'
Creator: Microsoft® Word 2016
Producer: Microsoft® Word 2016
```
- And the one that works was created with Office 365:
```
$ pdfinfo Info\ Note\ Mainstreaming\ gender\ and\ social\ differentiation\ into\ CCAFS\ research\ activities\ in\ West\ Africa-converted.pdf | grep -E '^(Creator|Producer)'
Creator: Microsoft® Word for Office 365
Producer: Microsoft® Word for Office 365
```
