Are you running the Steam client beta?
I don't know. I was taking part when Steam4Linux was beta back then. Currently, I'm running the steam.deb file that is located at http://repo.steampowered.com/steam/archive/precise/steam_latest.deb as there is still no repo available for trusty.
About Steam dialog says nothing about beta: http://i.imgur.com/2DOqHMK.png
In client settings, "Account" section, switch your Beta participation to "Steam Beta Update". Can you list the contents and file sizes of ~/.local/share/Steam/ubuntu12_32/steam-runtime/i386/usr/lib/i386-linux-gnu/libxcb*? If you hacked the steam runtime files manually it's possible the update hasn't applied properly and you'll need to reset your steam client install with 'steam --reset'.
Note: I previously removed the libraries in order to fallback to the sys libraries in /usr/lib/.
Thanks for the help! Been there, done that. The update occured afterwards and all the libxcb libraries (including libxcb.so.1) were overridden with the newer ones. Afterwards I did a plain steam profile folders removal and install to verify it is working.
Issues with libxcb are gone now, but the dbus glib bindings are still outdated.

christoph@c2de:~$ strings /usr/lib/x86_64-linux-gnu/libdbusmenu-gtk.so.4 | grep LIB
GLIBC_2.2.5
LIBDBUSMENU-GTK
Summary: libxcb errors are gone with beta update from 1st May 2014, still having troubles with libdbusmenu-gtk.so.4. Using the fallback os-shipped libdbusmenu-gtk library solves the issues here.
What's the symptom caused by the older libdbusmenu-gtk binaries?
Seems as you are catching all the strace stuff after the "breakpad exception handlers" are installed. Dunno how to avoid that or disable that.
The PIDs of the processes are incorrectly maintained between the forks and the main process. The libdbusmenu-glib warnings occur a couple times and are not occuring again after a timeout.
Its behaviour is identical to the one described in the wxwidgets framework wherein they had troubles getting it to run with the global menu stuff and having some pointer/reference errors there due to segfaults: http://trac.wxwidgets.org/ticket/14292
I would guess in the blue that your behaviour is a pointer/reference error as well, might be related to the global menu, too. I would guess that because of this changeset that fixed the error in wxwidgets: http://trac.wxwidgets.org/changeset/73277

After spawning the game, the PIDs look like this:
christoph@c2de:~$ ps -ef | grep hl
christo+ 4630 4629 0 11:28 pts/1 00:00:00 /bin/sh -c "/home/christoph/.local/share/Steam/SteamApps/common/Half-Life/hl.sh" -steam -game czero

When closing the game, the PIDs are correctly maintained again (at least it seems so):

Sorry, I'm not following; what is the actual problem you're seeing outside of that spew?
Closing pending feedback.
Nothing extracted yet.
When will this issue be fixed? It's marked as fixed, but not shipped yet. After over 4 months. I mean, pretty all Linux users can't use the steam runtime at the moment.
See the other issues #3231, #3238, #3204
Updated a minute ago (Ubuntu 14.04 LTS), still having the identical issues as already reported. Don't want to comment an all the re-referenced bugs as someone closes it and it seems to never get fixed otherwise. I mean, there's already an arch wiki entry for overwriting the library due to no-reaction on your side (https://wiki.archlinux.org/index.php/Steam/Game-specific_troubleshooting#Game_does_not_start_with_libxcb-dri3_error_message)
You currently leave Linux users no other option than fixing it themselves and patching libraries. I wanted to avoid that, but I can't, as nothing happens on your side.
