Serveradmin takes wrong values and crashes service

Question

Hi
Serveradmin on console is taking wrong values and therefore crashing services. without checking syntax or possibility that the value I just set may be wrong.
Backstory:
My calendarservice produced strange errors on the client side after upgrading from 10.7 server to 10.10 (I know it's a bit brutal, but over all it worked out (almost)), and finding no Logfiles in /var/log/calendar
So I found that this value was not set
# serveradmin settings calendar:LogLevels 
calendar:LogLevels = _empty_dictionary
And so i Set it to
# serveradmin settings calendar:LogLevels  = warn
And after wards the Service was unable to do ANYTHING
Oct 28 10:14:54 server com.apple.xpc.launchd[1] (org.calendarserver.agent[8730]): Service exited with abnormal code: 1
Oct 28 10:14:54 server com.apple.xpc.launchd[1] (org.calendarserver.agent): Service only ran for 1 seconds. Pushing respawn out by 9 seconds.
Oct 28 10:14:57 server com.apple.xpc.launchd[1] (org.calendarserver.calendarserver[8740]): Service exited with abnormal code: 1
Oct 28 10:14:57 server com.apple.xpc.launchd[1] (org.calendarserver.calendarserver): Service only ran for 1 seconds. Pushing respawn out by 59 seconds.
Oct 28 10:15:05 server com.apple.xpc.launchd[1] (org.calendarserver.agent[8756]): Service exited with abnormal code: 1
Oct 28 10:15:05 server com.apple.xpc.launchd[1] (org.calendarserver.agent): Service only ran for 1 seconds. Pushing respawn out by 9 seconds.
and serveradmin just printed out the following:
# serveradmin settings calendar
calendar = _empty_dictionary
The "solution" was to recreate the /Library/Server/Calendar\ and\ Contacts/Config/caldavd-system.plist file from a Timemachine backup. (directly via browsing into the path in the terminal) /Volumes/SOME_VOLUME/Backups.backupdb/HOSTNAME/DATE/HARDDISK//Library/Server/Ca lendar\ and\ Contacts/Config/...
There is even no need to restart or anything, the server app immediately was able to recognise the file and was starting up the service again.
I hope I could help anybody with that information, and maybe some apple devs may also read this and try to fix it. (or add it as a feature )
Now i can go on and try to fix the "real problem" again
Error 500 CalDAVAccountRefreshQueueableOperation
(fun fact... the problem seems to be gone as well... strange...)
