Assertion failure twophase.c (testing HS/SR)

9.0devel (cvs yesterday) primary+server, with this patch:
extend_format_of_recovery_info_funcs_v2.patch
( http://archives.postgresql.org/pgsql-hackers/2010-02/msg02116.php )

A large (500 GB) restore left to run overnight, gave the below crash. The standby was restarted,
and seems to be catching up OK.

LOG: entering standby mode

(btw, I think I have seen this exact same one (File "twophase.c", Line: 1201) a few times before,
without reporting it here, so it might have no connection to this particular patch. Sorry to be
vague about that)

Is it useful to report these cases of FailedAssertion?
