The bracktrace seems quite deep in mir.

[Daniel van Vugt (vanvugt)]

It appears the crash started happening on phones in Mir 0.21, which actually isn't in the stable channel yet. So expect this bug to explode after OTA-11 goes out...

No idea why it would crash though:

template <typename ProtobufType>
auto make_protobuf_object()
{
    return std::unique_ptr<ProtobufType>{ProtobufType::default_instance().New()};
}

Perhaps another manifestation of the Unity8 heap corruption bug 1535297?

[Daniel van Vugt (vanvugt)]

errors.ubuntu.com shows the bug either stopped happening on 31 May (just before OTA-11) or we stopped collecting data (?)

No offense... but this needs to be unassigned in order for the automatic expiration period to begin.

[Expired for Mir because there has been no activity for 60 days.]
