Is this a properly mangled name? When I run c++filt on it, it is unable to do 
the demangling.

Can you try to obtain the same stack trace from smth. like gdb and see if it's 
properly demangled there?

Yes, this is what I see in GDB:

#1  0x0000000000587d47 in Bind<void 
(dbus::ObjectManagerTest::*)(dbus::ObjectPath const&, 
std::__1::basic_string<char, std::__1::char_traits<char>, 
std::__1::allocator<char> > const&), 
base::internal::UnretainedWrapper<dbus::ObjectManagerTest>, dbus::ObjectPath>
