[Android Software Development] :
Ever since I flashed the Dec 6 Pico Opengapps package, Gmail, Email.app, and Whatsmore keep crashing. The first two crash whenever I try to open a particular email by tapping on it, the latter crashes upon launch (app verifies google license upon startup). Here's the crash log from Email.app:

Does anyone know if this is indeed Gapps related?

I'm on a HTC One S, running the CM12.1 October snapshot, and currently on the Dec 7 Pico Opengapps package.
