hobbitlaunch segfault / timewarp happend again

[Alexander Keller]

Hi Henrik,

in january I reported a segfault with hobbitlaunch/timefunc.c. You quickly
provided a patch...

Now I'm having a new error - see core dump:

I can reproduce the error with "ntpdate" using a misconfigured ntp server
(2 min in the past):

1. start hobbit client "runclient.sh start"
2. sync time with "ntpdate <misconfigured-time-server>"
3. get a core dump :-(
