[1431419911.659329] <ERROR> MirBufferStreamAPI: Caught exception at client
library boundary (in mir_buffer_stream_get_graphics_region):
/home/dan/bzr/mir/dev/src/platforms/mesa/client/client_buffer.cpp(63): Throw in
function {anonymous}::ShmMemoryRegion::ShmMemoryRegion(const
std::shared_ptr<mir::client::mesa::BufferFileOps>&, int, const
mir::geometry::Size&, mir::geometry::Stride, MirPixelFormat)
Dynamic exception type:

std::exception::what: Failed to mmap buffer
13, "Permission denied"
And that's running as root(!)
Workaround: Use the installed version 0.12.1 of mirscreencast on
vivid, which works still.
