When managed proxy dies, we get "Tried to connect through proxy, but proxy address could not be found."
In legacy/trac#5070, arma reported that if he puts:
```
ClientTransportPlugin obfs2 exec /bin/false --managed
```
in his torrc.
In his logs he gets:
```
Feb 10 03:29:57.000 [notice] Managed proxy stream closed. Most probably application stopped running
Feb 10 03:29:57.000 [notice] Failed to terminate process with PID '13672'
Feb 10 03:29:57.000 [warn] You have a Bridge line using the obfs2 pluggable transport, but there doesn't seem to be a corresponding ClientTransportPlugin line.
Feb 10 03:29:58.000 [notice] Bootstrapped 5%: Connecting to directory server.
Feb 10 03:29:58.000 [warn] Tried to connect through proxy, but proxy address could not be found.
```
The last line _Tried to connect through proxy, but proxy address could not be found_ is not very clear or helpful.
