network-stream-get-response returns nil if the server connection is
lost, hence network-stream-command does the same. There was one instance
of a blind string-match against the return value which would fail with a
STRINGP NIL error from time to time.

The attached patch fixes this.

2013-02-13  Didier Verna  <didier@didierverna.net>

	* net/network-stream.el (network-stream-open-starttls): Check that
	the response to the starttls-command is not nil before
	string-match'ing it.
