I know something about Ruby, but I have no clue about this behavior... :-( It seems that some code somewhere (not in apt-listbugs, perhaps in one of the libraries, I would say) is taking that comment, treating it as a String, and trying to invoke the `default' method on it. But the [String] class has no `default' method. The Hash class has a `[default]' method, but String is not a subclass of Hash... String is a subclass of Object, but the [Object] class has no `default' method. [String]: <https://ruby-doc.org/core-3.1.2/String.html> [default]: <https://ruby-doc.org/core-3.1.2/Hash.html#method-i-default> [Object]: <https://ruby-doc.org/core-3.1.2/Object.html> This should explain why trying to invoke the `default' method on a String generates an "undefined method" error. But it does not explain which code is trying to invoke that method... :-( I am tempted to reassign this bug report to package libruby3.0 (version 3.0.4-8) and let more knowledgeable people investigate.
