OK, I found a workaround. My task actually is inside a role. Therefore I
was able to define a default value for *some_dict*.
myRole/defaults/main.yml:
some_dict: {}
The condition still is ignored, but with no elements nothing is processed,
obviously.
Is there another solution to this? If this task would not be inside a role
(yes, I know you always should work with roles ;)) I wouldn't be able to
define a default value.
Cheers,
Daniel
