Many programs and basically all terminal emulators close all fds - urxvt
is kind of the exception (it is considered a feature useful for example
when embedding).

If it's not you, then it's most likely a bug somewhere else, e.g.
in gdm. It might actually be security relevant (or some very weird
"feature" in gdm, if it is gdm), so investigating it might help something,
somewhere.
