(address . bug-guix@gnu.org)
Some weeks ago, after running `guix pull` and `guix home reconfigure
~/.config/guix/home.scm`, my telegram-desktop stopped working. It showed
no error messages whatsoever, running it just didn't start a process.
Given particular circumstances, I did no further investigation, and did
not write a bug report, only switched the pull commit and reconfigured
my home.
Some days later, I guix pulled and reconfigured my home again, this time
to the latest commit, and telegram-desktop was fixed, but mpv was acting
exactly the same, since I didn't investigate the first time, can't
affirm it's the same problem, but seems plausible.

A friend on the #guix IRC channel tried to reproduce the error, but got
an working mpv, with the exact same hash.
