Kile (among others) does not find any dictionaries

[piegamesde]

Describe the bug Kile, and many other KDE applications, cannot find any dictionaries.

To Reproduce Steps to reproduce the behavior:

1. nix-shell -p kate "(pkgs.aspellWithDicts (d: [d.en d.de]))" --run kile
2. Tools > Spelling > Change Dictionary

Expected behavior The combobox contains a list of all English and German language packages.

Actual behavior

The list empty.

Screenshots

Additional context I know there are a lot of issues of this kind in Nix (with LibreOffice as well I think). But I fear we'll need a solution for almost each application and dictionary library pair (maybe we can fix all KDE applications at once as they share the editor code).

I'm not even 100% shure if Kile uses aspell, I think it uses a KDE-specific middleware that may have different backends.
