What's new in at-spi2-core 2.3.4: * Add some dbus message signature checks. * Fix a crash if a device listener incorrectly returns a non-bool. * Fix for BGO#666870: Keystroke listeners do not work unless an event listener is also registered [also needs updated at-spi2-atk] * Fix for BGO#667254: Some atspi-selection_* functions were broken. * When a call times out, ping the connection and avoid making subsequent calls until the ping is answered.
