tor 0.1.2.17 server died after only a few hours

[Scott Bennett <bennett@xxxxxxxxxx>]

     I switched from 0.1.2.16 to 0.1.2.17 this morning.  About 5 hrs. 20-odd
minutes later, tor wrote the following message to the notice log and exited:

Sep 04 14:06:29.140 [err] connection.c:2387: assert_connection_ok: Assertion connection_is_writing(conn) || conn->wants_to_write || (conn->type == CONN_TYPE_DIR && TO_DIR_CONN(conn)->is_blocked_on_or_conn) failed; aborting.

Does anyone know what caused this?  I can still switch back to 0.1.2.16 if
need be.
