The tail Hinzugef� indicates an issue with the german umlaut ü in the word Hinzufügen.

experienced with 2.0.0.dev6963+9666781+201703011947~ubuntu16.10.1

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.

[Cas]

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.

[krichter]

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