Two semi-recent cases:

Five months because of § 167 I S. 1 - disruption of service (and vandalism).

In this case the two men disrupted ca. 50 events earlier.

A conviction of a couple to a fine of 1,800 Euro because of § 167 I S. 2 - insulting nonsense.

They posted photographs of themselves being naked in  an empty church. A catholic "accidentally" discovered the photos in an erotic forum and made an anonymous complaint.

The two serial disruptors were somewhat religious motivated, so in both cases we don't speak about political actions .
