Comment(by rransom):

 Replying to [comment:13 karsten]:
 > See updated branch fix2183 in my public repository. This patch takes the
 (hopefully more robust) approach of joining smartlist elements to generate
 the extra-info descriptor.

 Your patch uses `log_err` to report conditions that will not crash Tor.

 From src/common/torlog.h:
 {{{
 /** Error-level severity: for messages that only appear when something has
 gone
  * very wrong, and the Tor process can no longer proceed. */
 #define LOG_ERR     3
 }}}

 We are considering handling messages with level LOG_ERR specially in
 response to the current fix for #1125 -- in particular, the process of
 logging error messages may itself destabilize or crash the Tor process, in
 an attempt to report a useful error message to Windows Tor users who can
 only read log messages through Vidalia.
