Bug#691018: libatk-bridge2.0-0: [experimental] closes a shared libdbus connection
Package: libatk-bridge2.0-0
Version: 2.6.0-1
Severity: normal
Since upgrading to Gtk and ATK from experimental, some Gtk applications
(including gedit and evince) print this warning on exit:
process 24460: Applications must not close shared connections - see dbus_connection_close() docs. This is a bug in the application.
gdb reveals that the only call to dbus_connection_close is from the ATK
bridge.
Applications using libdbus may only close private D-Bus connections,
obtained with dbus_connection_open_private() or dbus_bus_get_private().
They must not close global shared connections, which come from
dbus_connection_open() or dbus_bus_get().
I haven't yet checked whether this is fixed in 2.6.1.
