When starting kid3-3.7.0-1.fc29.x86_64 it shows a popup "Ambiguous Shortcuts: [...] Please report it in bugs.kde.org". However the issue tracker seems to not be bugs.kde.org but Sourceforge.
This is indeed hard coded in a KDE library, see the source code, so this cannot be fixed. If you are not using KDE as a desktop environment, I recommend using kid3-qt instead of kid3. With KDE, I have not seen such a message when using the default keyboard shortcuts.
If you would like to refer to this comment somewhere else in this project, copy and paste the following link:
Thanks for the report. I will have a look at it, but I expect that this message comes from a KDE library and cannot be changed
