 - [CIMMYT's DSpace repository](https://repository.cimmyt.org/) is now running DSpace 5.x!
 - It's running OAI, but not REST, so I need to talk to Richard about that!

+- I see there was an update to Ubuntu's ImageMagick on 2018-10-05, so maybe something changed or broke?
+- I get the same error when forcing `filter-media` to run on DSpace Test too, so it's gotta be an ImageMagic bug
+- The ImageMagick version is currently 8:6.8.9.9-7ubuntu5.13, and there is an [Ubuntu Security Notice from 2018-10-04](https://usn.ubuntu.com/3785-1/)
+- Wow, someone on [Twitter posted about this breaking his web application](https://twitter.com/rosscampbell/status/1048268966819319808) (and it was retweeted by the ImageMagick acount!)
+- I commented out the line that disables PDF thumbnails in `/etc/ImageMagick-6/policy.xml`:
+
+
+```
+  <!--<policy domain="coder" rights="none" pattern="PDF" />-->
+```
+
+- This works, but I'm not sure what ImageMagick's long-term plan is if they are going to disable ALL image formats...
+- I suppose I need to enable a workaround for this in Ansible?
+- Also I note that for a few days the item views on DSpace Test are broken... I think Sisay must have been doing something
