So a few thoughts:

as we are dealing with potentially corrupted memory. I don't think we should
take this approach.

Ok, task is for Qt clients to intercept the sigsegv signal, and in a
handler close the mir connection which should release all its video
buffers, then re-raise segv. Would it be of interest to have all mir
clients exhibit this behaviour by default? If so, should put this

some thoughts upon analysis of /usr/share/apport/apport:
- apport does have support for blacklisting crash reporting for specific
