Yeah this seems to be a duplicate of #2978

Can you backup and remove de/LC_MESSAGES/deluge.mo and see if it fixes the issue? If it does can you zip and attach the file here.

[Calum]

Ok so I found an issue with the mo files being created by msgfmt so I have pushed a fix: [d1daeb4cb0]

It should propagate to develop PPA build sometime tomorrow.

[Karl Richter]

This is fixed in PPA version 2.0.0.dev6980+d1daeb4+201703170531~ubuntu16.10.1 on Ubuntu 16.10. Thank you!
