I just upgraded docker image from 0.9.4 to latest.
This looks like some issue with my DB. I start with:
```
docker run   -p 4242:4242 -p 8042:8042 -v /data2/orthanc:/var/lib/orthanc/db  -v /home/ubuntu/orthanc.json:/etc/orthanc/orthanc.json:ro jodogne/orthanc-plugins /etc/orthanc/orthanc.json --verbose
```
If I remove ` -v /data2/orthanc:/var/lib/orthanc/db`, the server start.
