After the latest schema update, a user observed breakage with libmusicbrainz 4.0.1 which goes away when upgrading to 4.0.2 https://bugzilla.redhat.com/show_bug.cgi?id=822177

16:57 < adhawkins> I wonder if seeing an invalid tag in the XML response stops
it processing the rest of the entity?
16:57 < teuf> ah maybe s-j parsing code is too strict
16:57 < adhawkins> There is a new 'number' tag that is text. 4.0.1 won't know
what to do with that.
16:57 < adhawkins> I thought it just emitted an error and then continued, but
I could be wrong.
16:58 < adhawkins> Or perhaps the library is getting it wrong if it doesn't
understand the response.
16:58 < adhawkins> If you can raise it as a ticket in JIRA with the exact
query that's being sent, I can investigate.
16:58 < warp> adhawkins: in general you should ignore unrecognized elements,
not emit errors
16:59 < teuf> adhawkins: yeah trying to get this info
16:59 < adhawkins> warp: Which element is the new 'number' tag part of?
16:59 < ocharles> <track>
16:59 < warp> adhawkins: <track>
16:59 < adhawkins> Ah yes, found it. Looking
17:00 < adhawkins> I think it'll write to stderr for the unrecognised element,
but should then continue I'd have thought.
17:01 < adhawkins> Ah hold on.
17:01 < kepstin-work> adhawkins: well, boot up an older version of
libmusicbrainz and give it a try
17:01 < adhawkins> Looks like some shortcutting might be going on.
17:01 < adhawkins> Yeah, I think once it sees something it doesn't recognise
it will ignore everything else.
17:01 < adhawkins> Not a good plan.
17:02 < kepstin-work> ouch, that's a nasty bug.
17:02 < kepstin-work> is that bug still in 4.0.2?
17:02 < kepstin-work> if so, you really should put out a 4.0.3 with it fixed.
17:02 < adhawkins> Yes, but 4.0.2 should recognise everything
17:02 < kepstin-work> not after the next schema change release
17:02 < adhawkins> I already need to do a 4.0.3 with a fix for the compilation
error.
