Tobias,

first of all I have to add that on my laptop, with the very same
channels and manifests configuration, I'm not experiencing this issue.

Yesterday I did a garbage collection via "guix gc", could have been
this? ...probably not

> If not, could you grep your ~/.cache

I did a "find ~/.cache -type f -exec grep --color -nH --null -e
bi4m86lripz4fhhi4c34ylg5ckxsrqzs \{\} +" (via Emacs) and it found a
reference to that hash in this files:

AFAIU nothing related to my issue.

Nothing in ~/.local

Probably some qt related tool stored the (wrong/old) absolute path of
xdg-open and both nheko and quaternion on my desktop are using that
value when they try to open URLs... so yes, I'm almost sure the issue
is related to my environment/configuration.

...but what... where?!?

ehrm... forget it please :-D

...still investigating.
