Found by Christoph Diehl's "Faulty" fuzzer, see bug 777067
This is going to end up in IPC code I believe.
Component: Graphics → IPC

The problem is at:
#6 0x00007fffefa9ae27 in IDMap<mozilla::ipc::IProtocol>::AddWithID (this=0x7fffcd892260, data=0x7fffc9e3bb80,
id=-2) at /hack/mozilla-central/ipc/chromium/src/base/id_map.h:58
58 DCHECK(data_.find(id) == data_.end()) << "Inserting duplicate item";
Since this is generic IPC code that is used, in particular, in the parent process, the problem is a generic "IPC code should not crash parent process on bad pickles" similar to bug 963978.

Classification: PCompositor, generic "IPC code aborting in DEBUG builds on bad pickles" bug, easy.

This should be fixed by whatever global solution we can agree on in bug 963978
Depends on: picky-with-pickles
