Comment 1 Dan Sully 2005-03-22 18:02:38 UTC

Are they using iTunes?

Or have a playlist with non-existent tracks, perhaps?

Comment 2 Dan Sully 2005-03-23 00:26:43 UTC

Kevin - I checked in subversion change 2683, which should alleviate this issue.

We still don't know how a null track got onto the list though.

If they can reproduce this with their current build, I'd be interested.

Comment 3 Blackketter Dean 2005-03-23 16:04:21 UTC

Kevin, please reopen if it's not there anymore.

Comment 4 Kevin Pearsall 2005-03-24 14:54:44 UTC

he'll be trying it tonight.  i'll mark as verified if things go well...

Comment 5 Kevin Pearsall 2005-03-24 17:00:22 UTC

prs mailed me back saying things have been going well for a couple of hours.  i
asked him if he could let it run for a day or two and let me know, if all is
well i will mark verified then.  thanks!
