I recently updated to a more recent version of the 12.1 nightlies of Cyanogenmod on my Nexus 5. Everything Google related seems to work except Hangouts. When I open hangouts it crashes immediately. The logs seem to show an inability to write to data/data/com.google.android.talk and an inability to read the SQLite databases within (some exploration in the shell reveals that the folder is empty).

What I've tried:

1. Wiping the caches
2. Installing new versions of Gapps
3. Wiping data and cache for Hangouts
4. Installing Hangouts Dialer

5. chmod 757 on that folder

I see that just about every data folder has a unique owner and group, could hangouts have somehow gotten mixed up?
