The Xsession script for KDE 3.3.0_beta1 has some clever code that attempts to appropriately source the user's shell init files. That code doesn't work for me because Xsession is invoked as a regular /bin/sh script, and sh happens to be bash. So we have SHELL=/bin/bash BASH=/bin/sh and bash is basically operating in sh compatibility mode where not all bash extensions are supported. This leads to errors when the bash specific init files are loaded. For example, I have bash code like: function foo--bar() { ... } and, in sh compat-mode, I get complaints about foo--bar being an invalid identifier. I fixed it by changing /bin/sh to /bin/bash in Xsession, but, I guess, whereever Xsession is actually invoked, it should be invoked as $SHELL Xsession where $SHELL is the user's shell. I'd say it is a fairly severe issue because it causes users to not be able to log in; and that's about as broken as it can get from a user's perspective ;-) Reproducible: Always Steps to Reproduce: Portage 2.0.50-r9 (default-x86-1.4, gcc-3.3.3, glibc-2.3.3.20040420-r0, 2.4.26-gentoo-r5) ================================================================= System uname: 2.4.26-gentoo-r5 i686 Intel(R) Pentium(R) III Mobile CPU 1200MHz Gentoo Base System version 1.4.16 Autoconf: sys-devel/autoconf-2.59-r3 Automake: sys-devel/automake-1.8.3 ACCEPT_KEYWORDS="x86" AUTOCLEAN="yes" CFLAGS="-march=pentium3 -O2 -pipe -fomit-frame-pointer" CHOST="i686-pc-linux-gnu" COMPILER="gcc3" CONFIG_PROTECT="/etc /usr/X11R6/lib/X11/xkb /usr/kde/2/share/config /usr/kde/3.2/share/config /usr/kde/3.3/share/config /usr/kde/3/share/config /usr/lib/mozilla/defaults/pref /usr/share/config /usr/share/texmf/dvipdfm/config/ /usr/share/texmf/dvips/config/ /usr/share/texmf/tex/generic/config/ /usr/share/texmf/tex/platex/config/ /usr/share/texmf/xdvi/ /var/qmail/control" CONFIG_PROTECT_MASK="/etc/gconf /etc/terminfo /etc/env.d" CXXFLAGS="-march=pentium3 -O2 -pipe -fomit-frame-pointer" DISTDIR="/usr/portage/distfiles" FEATURES="autoaddcvs ccache sandbox" GENTOO_MIRRORS="http://ftp.belnet.be/mirror/rsync.gentoo.org/gentoo/ ftp://sunsite.informatik.rwth-aachen.de/pub/Linux/gentoo/ http://gentoo.oregonstate.edu/ http://www.ibiblio.org/pub/Linux/distributions/gentoo" MAKEOPTS="-j1" PKGDIR="/usr/portage/packages" PORTAGE_TMPDIR="/var/tmp" PORTDIR="/usr/portage" PORTDIR_OVERLAY="/project/ARCH/Projects/portage/configs/=build" SYNC="rsync://rsync.europe.gentoo.org/gentoo-portage" USE="X aalib alsa apm arts avi berkdb bonobo crypt cups dvd encode esd foomaticdb gdbm gif gnome gpm gtk gtk2 gtkhtml guile imlib java jpeg kde ldap libg++ libwww mad mikmod motif mozilla mozsvg mpeg mysql ncurses nls oggvorbis opengl oss pam pdflib perl png python qt quicktime readline sdl slang spell sse ssl svga tcltk tcpd tetex truetype x86 xml2 xmms xv zlib"
Perhaps a proper fix (to send upstream) would be substituting [ -z "$BASH" ] && exec $SHELL $0 "$@" with [ "$BASH" = "$SHELL" ] || exec $SHELL $0 "$@" (and for other shells, too) in Xsession (in kdebase/kdm/kfrontend/genkdmconf.c)
Yesterday I was bored, so I reported this bug upstream: http://bugs.kde.org/show_bug.cgi?id=85544
...and now fixed http://webcvs.kde.org/cgi-bin/cvsweb.cgi/kdebase/kdm/kfrontend/genkdmconf.c.diff?r1=1.89&r2=1.90&f=h
I like it when you're bored Gregorio. ;)
