Network Pref crash when you hower over a wlan name lan list

[modeenf]

Reproduce (easy)

• Open Network pref
• Go to the Wireless device
• Go to the Network Dropdown list. In my case I have problem choosing network but I have the same problem on a system that works.
• now hower over a network name (don't select). the list need to blink (update) and the it should chrach. On my working system I needed to wait for two-three updates before it craches (or if I howerd above other names).
