** Description changed: Impact: libmessaging-menu using apps can segfault when unloading and reloading code Test Case: - Write a libmessaging-menu client, unload and reload messaging-menu support, see if it segfaults or not + - download the file from comment #1 + - gcc test-app.c -o test `pkg-config --cflags --libs messaging-menu` + - run ./test + + with the fixed version it shouldn't segfault Regression Potential: Limited, check that the usecase is correctly supported --- I've been experimenting with adding messaging-menu support to an app through a plugin, and I've noticed errors/crashing when recreating the MessagingMenuApp object after having g_object_unref'd it, as in the situation where the user unloads the plugin, then loads it again. This is the error, which follows from pressing 'Plugin Load', 'Plugin Unload', 'Plugin Load' in the test application: ** (test-app:3805): WARNING **: unable to export action group: An object is already exported for the interface org.gtk.Actions at /com/canonical/indicator/messages/test_app_desktop (test-app:3805): GLib-GIO-CRITICAL **: g_dbus_connection_register_object: assertion `error == NULL || *error == NULL' failed ** (test-app:3805): WARNING **: unable to export menu: (null) I would include a stack trace but it is not consistent, so I suspect some sort of memory corruption (sometimes it doesn't crash at all, just spins at 100% and brings down compiz). I'm going to take a look at indicator-messages and see if I notice anything but I thought I'd post the bug first, maybe someone could immediately tell what the issue is, or suggest a fix in my code if I am not freeing the object correctly before recreating it.
