segfault caused by invocation of g_object_unref(G_OBJECT(cursor)) in response_callback(..), avahi-ui.c

[Vaxeij8e]

When running mango-lassi in Ubuntu 11.10, following line in avahi-ui.c, in function response_callback causes segfault:

g_object_unref(G_OBJECT(cursor))

Since cursors have their own unref functions, I replaced it:

gdk_cursor_unref(cursor);

With this fix in place no segfault occurs, and mango-lassi works as expected.
