Can we confirm this doesn't reproduce on 1.3?

Buri

Doesn't happen on Buri.  (At least not with the STR given).

Looking at John's dmesg log : 
<4>0[ 1453.730432] select 2517 (Calendar), adj 10, size 5852, to kill
<4>0[ 1453.730500] send sigkill to 2517 (Calendar), adj 10, size 5852

The Calendar app got killed.

I OOMed (app exits to homescreen) 5 out of 10 times when trying to edit and save any picture taken by the Tarako. According to bug 998095, the threshold of the edit function is around 310KB, and each picture the Tarako takes exceeds ~500KB.

With the 5 attempts that I didn't OOM, I could NOT reproduce this bug. The keyboard correctly invokes and responds to key pressings when adding an event on Calendar.
