Thank you for your explanation Wolfgang! Now it is clear to me. The issue is that the generator calls the close() method of the subgenerator, but if the subgenerator is a file, the close() method closes (surprise!) the file. Two different protocols use the same method.

Interesting, how many similar bugs was introduced by blindly replacing "for/yield" with "yield from"?
