Description of problem:
Although the NetworkManager service starts on boot, it fails and must be restarted manually in order to get network services.

Version-Release number of selected component (if applicable):
NetworkManager-0.9.4-6.git20120521.fc16.x86_64

How reproducible:
Happens most times the machine is booted, but not every single time.

Steps to Reproduce:
1.Boot system.
2.Log in.
3.Notice that there is no network icon, and that web browsing fails
4.System Settings -> Network says "The system network services are not compatible with this version"

Actual results:
Web browsing fails and network configuration is impossible.

Expected results:
Web browsing succeeds.

Additional info:
What seemed to fix it just now was 'systemctl restart NetworkManager.service', although I had also run ifconfig to set the wlan IP address, and iwconfig to set the essid (but had not yet set the required key).

There are log messages, and a coredump caught by abrt:
