Probably the reason is that I am doing things in a ‘pure’ environment
here:

$ guix shell --pure totem -- totem a-file.mp4

In a ‘pure’ environment, various environment variables are unset, which
avoids interference with other installed applications, which can be
usefel for debugging.  If you try "guix shell --pure totem -- totem",
you'll probably at least see the logo warning.

I don't expect it to be related to the issue you originally reported
though.
