Comment 6 for bug 1337529

I experienced this issue yesterday and I hadn't opened the system settings app. On talking to charles (indicator datetime developer) he thinks that this may be due to the phone constantly trying to suspend the phone which results in a race between the alarm playing event and the suspend event. So this bug is valid, but we are also tracking it at https://bugs.launchpad.net/indicator-datetime/+bug/1320877. So I am going to mark this as a duplicate rather than invalid.
