Bug Description

Recently I encountered a problem that my input method malfunctions because the environmental variables are wrongly set(which is, fully configured using im-config), after hours of debugging I found that it's Z-shell(my current default shell)'s bug that prematurely quits before the Xsession.d im-config input method configure script completes.

The problem is, /etc/X11/Xsession (and all the Xsession.d scripts it sourced) **shouldn't** be run in Z-shell. Patching /etc/kde4/kdm/Xsession # invoke global X session script. code from
. /etc/X11/Xsession
to
/etc/X11/Xsession

workarounded the issue (however I have no idea why). Switching to other display managers instead of KDM worked also)

Reproducible: Always

Steps to Reproduce:
Currently there's no simple reproduce method as another software(zsh)'s bug involved.

I found out that kdm runs /etc/kde4/kdm/Xsession using user's default shell.

It is not sane as in Xsession(5) manpage notes:
/etc/X11/Xsession is a Bourne shell (sh(1)) script which is run when an X Window System session is begun by startx(1) or a display manager such as xdm(1).
