I'm not sure this is fixable short of simply not using 3rd party code that throws exceptions. If it's fatal like this one is, we can't catch it and recover. We also can't modify the exception text to be more meaningful.

Josh Arenson and I were debugging a problem with a greeter / lightdm / unity-system-compositor. It turned out to be because lightdm was passing unity-system-compositor "--from-dm-fd=0" which resulted in an asio exception when it tried to use fd 0. But the exception looked like: """ ERROR: Throw location unknown (consider using BOOST_THROW_EXCEPTION) Dynamic exception type: boost::exception_detail::clone_impl<boost::exception_detail::error_info_injector<boost::system::system_error> > std::exception::what: assign: Operation not permitted """ It took us a surprising amount of effort to track down where this was actually failing (which was the usc::AsioDMConnection::AsioDMConnection constructor in src/asio_dm_connection.cpp). I don't have a suggested fix, just a request to make similar failure- hunts easier. Or at the least, this specific error case more obvious.
