KDE try to access /proc/self/maps

Hello everyone,

For some time now I have been seeing this message appearing very often in my journal:

I don't really know what is producing this message (while doing my research I started to assume it wasn't KDE itself but Firefox with DRM - since i use systemd to initialize plasma as described here, but I'm not sure). I would like to know if any of you have any leads or even experienced the same problem.
Thank you in advance!

Firefox Dev Edition : 89.0b14-1
KDE Plasma : 5.21.5
KDE Frameworks : 5.82.0
kernel : 5.12.5-arch1-1

Re: KDE try to access /proc/self/maps

Updare: I am now sure that this is related to the Firefox Widevine plugin. I think I'll open an external bug report since it obviously has nothing to do with Arch nor KDE.

A bug report is opened here for those who may be interested.
