Jira issue originally created by user gedrox:

Currently ID hash is generated using implode function with space character. I would like to point out that problems may raise if the ID column values are allowed to contain the space themselves - different objects could return equal ID hash values.

The trivial one-line solution would be to serialize the array instead. Cheaper solution from performance perspective would be escaping the space character for ID values.
