restart-vidalia appears to occasionally fail to actually restart Vidalia

While working on #9518 (closed) (in which I’m requesting Tor to use a new circuit in vidalia), my tests failed because vidalia was not running.

restart-vidalia was run and should have started vidalia, but for whatever reason it was not running.

spawning as root: restart-vidalia
spawn returned: [0, "", ""]
calling as amnesia: gpg --batch --keyserver-options import-clean --recv-key '10CC5BC7'
call returned: [2, "gpgkeys: HTTP fetch error 35: gnutls_handshake() failed: A TLS fatal alert has been received.\n", "gpg: requesting key 0x10CC5BC7 from hkps server hkps.pool.sks-keyservers.net\ngpg: no valid OpenPGP data found.\ngpg: Total number processed: 0\n"]
Forcing new Tor circuit...
calling as root: pidof -x -o '%PPID' vidalia
call returned: [1, "", ""]

But why wasn’t it running?
