Bluetooth support in new firmware for WP77xx R11 seems to be not complete:
process 2559: arguments to dbus_connection_get_object_path_data() were incorrect, assertion “connection != NULL” failed in file …/…/dbus-1.10.10/dbus/dbus-connection.c line 5904.
This is normally a bug in some application using the D-Bus library.
D-Bus not built with -rdynamic so unable to print a backtrace
could you please provide patch?
