211: context_node_node_update($node) - Assumes revision information

In a use case where another module is calling hook_node_update it is possible for revision information not to be passed.

Should the presence of '$node->revision' be assumed?

In a situation where we are using entity reference module and updating node parents in a custom module via a call... the following errors were generated.

Should the 'context_node_node_update($node)' function on line 211 rightly assume that '$node->revision' will or should always be available?

If no then this patch might be incorporated into the module.
