serf error handling problem

In gdb I see that this happens on pool cleanup when exiting the
application.  The sequence is:

svn_ra_serf__open calls serf_connection_create which adds a cleanup
handler clean_conn which will do serf_connection_close.

svn_ra_serf__create_handler adds a cleanup handler handler_cleanup which
will do serf_connection_reset.

The request fails and the program starts to exit.

The clean_conn cleanup runs and closes the connection.

The handler_cleanup cleanup runs and attempts to reset the connection
and gets a SEGV.
