file extension `lol' cannot be used twice

[ThexXTURBOXx]

After updating my local MiKTeX installation, I encounter the following error: ! Package tocbasic Error: file extension lol' cannot be used twice .` (full log at the bottom of this issue).

I researched a bit and dug through my local files and my MiKTeX backup before updating and found that the listing package added the following line in 1.10a: \def\ext@lstlisting{lol}

So, I was able to boil this issue down to two packages: listings and minted in conjunction with KOMA scripts.
The following MRE encounters the error described above:

\documentclass{scrbook}

\usepackage{listings}
\usepackage[newfloat]{minted}

\begin{document}

\end{document}

It should be noted that the issue can be fixed by removing the newfloat option from minted, which leads me to the suspicion that I should also report this error somewhere else...
However, for now, the issue is probably correct here - please let me know if you think otherwise.

[komascript]

Package tocbasic provides a security mechanism to prevent unwanted usage of the same auxiliary file for different lists. Both listings and minted use the same file extension lol. IMHO in this case this is wanted. But with option newfloat package minted uses package newfloat to define a new float with a new file extension.

Note: newfloat correctly uses tocbasic's \addtotoclist to register file extensions, if the command exists.

To avoid the problem, either minted should prevent the second registering of the extension if listings is loaded, or listings should prevent the second registering of the extension if minted is loaded (I will ask Jobst Hoffmann to do so).

As a workaround, you can use:

\documentclass{scrbook}
\usepackage{listings}
\usepackage[newfloat]{minted}
% Add the following lines, wherever you want.
\makeatletter
\AddToHook{begindocument/before}{\@ifpackageloaded{minted}{\removefromtoclist[float]{lol}}{}}
\makeatother
\begin{document}

\end{document}

or simply:

\documentclass{scrbook}
\usepackage{listings}
\usepackage[newfloat]{minted}
\removefromtoclist[float]{lol}% must be after loading `minted`.
\begin{document}

\end{document}

[ThexXTURBOXx]

@komascript A response from the guy himself, very nice to see! Thank you very much for your explanation!
This whole issue makes sense to me now and I will be patiently waiting for a fix.
Maybe it is better to close this very issue here then - since the fix should apparently rather land in listings.
However, I let the maintainer(s) here decide and leave it open for the time being.
I also wanted to write an email to Jobst Hoffmann about this issue yesterday, but I wanted to first try to get a response here.
So, you can gladly go ahead and email him about this - or if you have something better to do, I can also do so!

[komascript]

The collaboration with Jobs works very well. He is primarily interested in facilitating solutions — just like me. That's why I've already wrote him and suggested a (somewhat more universal) change to listings.

In the end, it is only important that an extension is registered exactly once. Otherwise, for example, chapter spacings would be entered several times in the directory. This is why tocbasic also refuses multiple registration.
