Since the GNOME 44 upgrade, Epiphany no longer works for me (I’m using
EXWM, not GNOME):

Stracing shows this:

  10989 execve("/run/current-system/profile/sbin/dbus-launch", ["dbus-launch", "--autolaunch=a6bada0da851047b698"..., "--binary-syntax", "--close-stderr"], 0x5d7120 /* 81 vars */ <unfinished ...>

Since I no longer have GDM either,
/run/current-system/profile/sbin/dbus-launch is gone, too (that’s
probably the main reason).

I’m not sure where this hard-coded /run/current-system/… comes from.
Should we do something about it?
