Description arne anka 2019-03-13 11:53:51 EDT

Task List View -> New Task
opens an editor and already throws an NPE, stack trace below.
Typing in the Name field (where there's initially "New Task") throws the same NPE for each key.
Saving the task results in the name being empty (no matter what I've typed in), and after that no change causes the Save action to be enabled again.

It's not possible to create tasks at all.
