Package: emacs-gtk
Version: 1:30.1+1-6
Control: affects -1 aspell-de
Distribution: Debian trixie.
How to reproduce:
1) Open an empty or a new file in emacs.
2) Type in the following German sentence without the quotation marks: “Wir sprechen von Zustanden in diesem Fall.”
3) M-x ispell- change- dictionary[ Enter] german[Enter]
In this step, any of the dictionaries “german”, “german8”, “deutsch”, or “deutsch8” would do.
4) M-x ispell-buffer
5) Observe that no spellcheck error is reported. On the contrary, I expect that "Zustanden" be marked as an error and two possibilities be suggested: “Zuständen”, which would make sense semantically, and “zustanden” as the past tense of "zustehen", though it would make no sense semantically. The word “Zustanden” with a capital letter would make sense only at the start of the sentence and not here in the middle of a sentence.
To check whether spellchecking occurs at all, type in a non-word, say, “foo”, in an extra line, issue M-x ispell-buffer, and observe that emacs reports “foo”.
6) M-: ispell-program-name[Enter] reports "aspell".
aspell-de 20161207-15 is installed. I might have reported it upstream several years ago, but it ended up nowhere. I kindly ask the Debian maintainers to push or fix the issue.
