where is the problem ? 

On a specific installation there will be one dbus installation say 1.2.9 
which includes the fix, but the fix is disabled by default. Also there 
is one Qt (with Dbus) installation which checks first if 
dbus_set_api_poliycy is available (QtDbus checks presence of every dbus 
api function) and if so activate the non thread safety fix.

All processes using this QDbus installation will be protected by the 
acticated fix.

Other bindings or low-level apps, which may requires patching, have to 
call dbus_set_api_policy() to activate this fix.
