This issue has been resolved by uploads 0.1.58 (testing/unstable) and  
0.1.56~deb12u2 (bookworm). Unfortunately, I forgot to mention this in  
d/changelog when uploading.

@Guido: please always(!) put the "Closes #XXXXXX" statement always in  
the first line of a Git commit. Otherwise gbp dch won't add it to  
d/changelog. Furthermore: multi-line/-paragraph Git commits are not  
handled well by gbp dch (the tool with which we create d/changelog).  
Those lines get simply ignored and I tend to forget moving over  
additional information from the Git commits over into d/changelog.  
Please help, easing the d/changelog creation workflow. Thanks!

Greets,
Mike
