Details

Steps to reproduce:
 1) Apply attachment 8386769 [details] [diff] [review] from bug 980317.
 2) Select debug builds on all platforms in the trychooser.
 3) Push to try.

Expected results:
Green build on all platforms.

Actual results:
B2G ICS emulator build fails (but B2G JB emulator build succeeds!), because conversion from nullptr to nsIContentHandle when nullptr is passed as an argument to a method that takes nsIContentHandle is ambiguous despite there being the relevant constructor taking mozilla::NullptrT.
You probably should not be using NullPtrT, see the comments here: <http://mxr.mozilla.org/mozilla-central/source/mfbt/NullPtr.h#75>

Yeah, your use of NullptrT isn't in accord with the intent/meaning of NullptrT.  I commented in the other bug on how to address things, it looks like it's more or less possible.
