> http resp_mime_types (accessed via: connection$http$resp_mime_types) are no longer initialized during the file_over_new_connection event. This is new behavior between Bro v2.3 and git/master.
> The following snippet shows the new behavior on one of the included bro test traces.
> {code:bash}
> $ bro_v23 -e 'event file_over_new_connection(f: fa_file, c:connection, is_orig:bool){ print c$http?$resp_mime_types; }' -r bro/testing/btest/Traces/http/get.trace 
> T
> $ bro_git -e 'event file_over_new_connection(f: fa_file, c:connection, is_orig:bool){ print c$http?$resp_mime_types; }' -r bro/testing/btest/Traces/http/get.trace 
> F
> {code}
> It's worth pointing out that ultimately the resp_mime_types field does get set for subsequent events.
> {code:bash}
> $ bro_v23 -e 'event http_message_done (c: connection, is_orig: bool,  stat: http_message_stat){ if (!is_orig) print c$http?$resp_mime_types; }' -r bro/testing/btest/Traces/http/get.trace 
> T
> $ bro_git -e 'event http_message_done (c: connection, is_orig: bool,  stat: http_message_stat){ if (!is_orig) print c$http?$resp_mime_types; }' -r bro/testing/btest/Traces/http/get.trace 
> T
> {code}
