Security Setting Crash

[anon(301129)]

I am on 4.2.2 and my security settings no longer works on my unlocked and rooted Nexus 4. It crashes each time I try to access.
It may have started after I installed my Gotcha Facetrap app. I can access part of the security tab (passwords only) through the facetrap app but can not get to the rest of the security items.
I have tried to uninstall the app and reboot but to no avail.
All I really want to do is enable the install from unknown locations.

Anybody have some ideas how to fix? Maybe through adb? I hate to wipe and reinstall everything.
Looking forward to suggestions and ideas.

I found that compared to my Nexus 7, which is working fine, the Nexus 4 has all the Device Administration area greyed out when I access it through the Gotcha app. Any idea how to get Device Administration rights back?
