Status update:
We are not able to reproduce this issue yet.  The stack trace indicates that 
you are receiving an unexpected code point "-2147482933".  Are you using a 
custom keymap file on your device?  If so, can you tell me what keyboard layout 
is selected on your device?

OK.  Now I'm able to reproduce the reported issue reliable.  Seems that the 
original report lacked some important steps.

Steps to reproduce:
1. Flush KTU84P to Nexus5
2. Install Mozc 1.15.1874.102 (r328)
3. Attach USB US hardware keyboard to phone
4. In the system hardware keyboard settings, Choose "English (US), 
International style" (see the attached screenshot: 
system-hardware-keyboard-layout.png)
5. In the Mozc hardware keyboard settings, choose "System Default" (see the 
attached screenshot: mozc-hardware-keyboard-layout.png)
6. Select a text input field
7. Press the ` key

Note that this is not specific to Android 4.4.  I can reproduce this issue on 
Android 5.0.  Updated the summary accordingly.
