"Controller uncleanly shut down" with no explanation, unless "angel" process is disabled

[charles-dyfis-net]

Observed in a pre-configuration state. Haven't tested whether this still happens after a config file exists.

I'd be happy for pointers on how to debug this (I imagine that to use a debugger I'd want to directly invoke the supervisee rather than the supervisor?):
