Subject: [PATCH 3/3] Issue 4581 - A failed re-indexing leaves the database in
broken state (#4582)
Bug description:
During reindex the numsubordinates attribute is not updated in parent entries.
The consequence is that the internal counter job->numsubordinates==0.
Later when indexing the ancestorid, the server can show the progression of this
indexing with a ratio using job->numsubordinates==0.
Division with 0 -> SIGFPE
Fix description:
if the numsubordinates is NULL, log a message without a division.
