Thruk/ShinkenUI downtime inconsistency - can't add a new downtime

[beuc]

For this last comment, I think I got confused with how "flexible" downtime works, sorry about that

Since then I got a few more "depth=-1" situations, including one that caused a 'maintenance_period' to be ignored, but I can't figure out what chain of actions trigger it.
(note: only by using Thruk)

The problem still exists and can be easily reproducible by running this command on Shinken's livestatus module:

id=118 ; for i in {1..10}; do echo "COMMAND [`date +%s`] DEL_SVC_DOWNTIME;$id"|netcat localhost 50000; done

Where id 118 is a valid downtime id.
For viewing scheduled_downtime_depth you can also run:

echo -e "GET services\n Filter: scheduled_downtime_depth != 0 \nColumns: host_name service_description downtimes scheduled_downtime_depth"|netcat localhost 50000
