So I fear the problem is still there.
As far as I understand, that assertion seems to be too strict.
Apparently, someone else already removed the task. Perhaps, all calls
to runqueue should be preceded by a check about the existence of the
task itself. An excerpt of that slapd instance's logs indicates:
