Comment (by cypherpunks):

 It seems like trying to set things like `SocksPort` to a UNIX domain
 socket will cause Tor to crash due to this bug. The path is whitelisted at
 compile-time, so changing it results in a violation and a confusing error
 suggesting that the path may not be readable.

 Other affected parameters that are broken when the sandbox are in use
 include:

 `DirPortFrontPage`
 `ServerDNSResolvConfFile`
 `CookieAuthFile`
 `ExtORPortCookieAuthFile`

 And likely more.
