PHP notice in cache_invalidate_clear_definition()

Problem/Motivation

When updating a node triggers cache_invalidate module to invalidate a cached item, I get this PHP notice:

Notice: Undefined offset: 2 in _cache_invalidate_process_node() (line 118 of [docroot]/sites/all/modules/cache_invalidate/cache_invalidate.module).
 

Proposed resolution

Remove integration with domain module. Module domain_views does provide a time-based Views cache plugin (domain_views_plugin_cache_time), but the cache key built by that plugin does not allow one to flush Views' output that matches a certain domain ID. The domain ID (along with other metadata) is hashed into a string, and that string is appended to the cache key. Unless cache_invalidate has all this metadata, I don't see how it can re-build the cache key in order to invalidate its cache item.
