Crash on 3.13.0-19 due to false libdbus and libxcb-dri (xcb_send_fd) usage. Not any single game startable.

[cookiengineer]

It seems as the libdbus API is not correctly used. There are always the same warnings that prevent steam from launching or killing another process (forks, probably). It seems as the xcb_send_fd method is deprecated as the symbol isn't found in the current library.

Please note that the whole OS relies on the libxcb-dri2-0 package, as the xorg depends on it. So there's no way to test out the behaviour of the old one compared to the new without garbaging the installation.

Bug Behaviour

First, I launched steam. After the update verification, I needed to go to Add Friend > Library > Linux Games > Condition Zero. Starting the game results in the following log (cutted down):

It seems as you have implemented a queue stack that a loop tries to work on. This queue fails and runs into exactly 42 process kill trials.
