Default amarok bug in 10.04

Quick heads up. Only ubuntu seems affected, not Kubuntu *shurg*

For the time being we'll be waiting if a specific file causes this, and if so,
try to get hold of it, so that debugging this becomes more of a non-guessing
job.

[19:07:14] <jefferai> apachelogger: hey Kubuntu dude
[19:07:24] <jefferai> you *buntu folks seem to have screwed something up
[19:07:44] <jefferai> lots of bug reports coming in from *buntu 10.04 users
against Amarok, and only from *buntu 10.04 users, and all with the same
problem
[19:08:27] <apachelogger> jefferai: the problem being?
[19:08:51] <jefferai> it's in the collection scanner
[19:08:54] <jefferai> sec
[19:09:20] <jefferai> https://bugs.kde.org/show_bug.cgi?id=236052
[19:09:32] <jefferai> and
[19:09:33] <jefferai>
https://bugs.launchpad.net/ubuntu/+source/amarok/+bug/572432
[19:12:49] <apachelogger> jefferai: could it be that the exception comes from
taglib?
[19:12:58] <jefferai> possibly
[19:13:07] <apachelogger> although
[19:13:07] <jefferai> although I don't know of taglib throwing any exceptions
anywhere
[19:13:14] <apachelogger> yeah
[19:13:25] <apachelogger> also we only updated taglib a week or 2 before
release
[19:13:30] <sandsmark> I thought taglib was qtish and didn't use exceptions?
[19:13:36] -*- apachelogger thought that maybe that caused it ^^
[19:14:01] <jefferai> yeah, I don't think taglib uses exceptions
[19:14:08] <apachelogger> anyhow
[19:14:12] -*- jefferai notes that not using exceptions isn't really qtish so
much as not-Javaish
[19:14:12] <sandsmark> from that bug it looks like it is glibc that's throwing
it
[19:14:22] <sandsmark> because you're trying to allocate too much memory
[19:14:26] <sandsmark> or to an invalid address, it seems
[19:14:29] <apachelogger> what is most interesting is that I do not encounter
that issue even though I regularly blow up my database and need to do a rescan
[19:14:48] <jefferai> apachelogger: I've never had that issue...only buntu
10.04 users are having it
[19:15:00] <jefferai> I did ask them to try narrowing it down to specific
file(s) causing it
[19:15:03] <sandsmark> does ubuntu turn on some funky stuff for glibc?
[19:15:13] <sandsmark> terminate called after throwing an instance of
'std::bad_alloc'
[19:15:14] <sandsmark> what(): std::bad_alloc
[...]
[19:18:48] <sandsmark> so I think the collection scanner is trying to allocate
too much memory
[19:19:01] <jefferai> that's not likely
[19:19:08] <jefferai> it's more likely that either taglib or qt is
[19:19:13] <sandsmark> well, maybe
[19:19:29] <jefferai> regardless, I really need a file that is trigger this...
[19:19:33] <jefferai> *triggering
