Look closily.  If the id was the only one in the list,
ldbm_cache_delete() is called.  If the id isn't the only
one on the list, the id is removed using SAFEMEMCPY()
and stores the new list using idl_store().

It's actually storing a list of ids.

This only changes behavior when the id is in a direct IDList.

It's probably better to change the caller to ignore the error
(after logging it).  I'll commit such a change to -devel.

It could have been deleted by a prior delete operation that
failed.  Hence, ignoring the error is likely the most appropriate
solution for now.
