When plugin calls plugin_set_key_group() several times for the same group (when creating keybindings dynamically and needs to reset them), it crashes with the current code the second time it gets called.
The reason is that group->plugin_keys is an array into which entries of group->key_items point and when calling
g_ptr_array_set_size(group->key_items, 0);
it calls free_key_binding() for every item - when these items are deallocated by g_free(group->plugin_keys) previously, calls of free_key_binding() reference an invalid memory.
Just first resizing group->key_items (and calling free_key_binding() for its items) and freeing group->plugin_keys afterwards fixes the problem. You can view, comment on, or merge this pull request online at:
