Thank you very much Chris, commenting out the two lines did the trick.
For me this looks like an obvious bug, the text of the changelog is
added after the line to close the entry and not before, as it should be.
The real fix would be to move line 339 and 340 before line 338 and in
addition do the following search and replace on this->changelogtext:
this->changelogtext =~ s/^(\s+)--(\s+)/$1-$2/m;
This should eliminate "end of changelog entry" character of the lines of
the inserted changelog text.
