I couldn't get debug symbols for libgobject, probably cause of grafts
and kinda gave up on this issue, sorry.

For the whole time we were using this fix in rde:
https://git.sr.ht/~abcdw/rde/tree/8d6a6b47/src/rde/features/emacs.scm#L217

And recently (a few minutes ago) I found out that the problem
dissapeared, so I don't need this fix anymore.  IDK, if it is due to
chromium version update or emacs.

Thank you very much for pinging! :)

I will report further in case it reappears.
