Try a different GAPPs package and see if that fixes the FC.

I pulled the aosp keyboard from cm11 and installed it on top, works fine now.
This ROM has been running great for me (better than CM11) and I love the options, but no USB car dock audio is killing me, I use the dock daily. I could just use the headphone jack with a 3.5mm aux cable, but it defeats the purpose of the car dock IMO.
Edit:
Upon reboot the keyboard reverted. I had to install the cm version again, then used TB to "integrate app updates into ROM". Works fine after reboot now. An easier way may be to uninstall the included keyboard, then install the cm version as a system app.
