Music app doesn't show shared files

[MorrisJobke]

Expected behaviour

When sharing music, it should also appear in the Music app of the user it is shared with.

Actual behaviour

Music shared by user A with user B does not apper in user B's Music app.

Steps to reproduce

1. As user A, make sure you have some mp3's which show up correctly in the Music app
2. As user A, share some of these mp3 files with user B
3. Login as user B
4. Check the FIles app: The mp3 files from user A are correctly shared
5. Check the Music app: The shared files will not appear

Notes

See also this forum thread: http://forum.owncloud.org/viewtopic.php?f=23&t=9499
Is this maybe a general problem of all apps? Because the Pictures app seems to have it too: owncloud-archive/apps#630

I get the same error: "Undefined offset: 1 at /var/www/owncloud/apps/gallery/ajax/gallery.php#12"

However I see different behavior and a have a little more data to offer around the scenario. I only see this error when I open the Owncloud website from Safari on a Mac client. It works fine from Chrome on the Mac and on a Linux client. The behavior is that I can see the music files (which are m4a files) in the player. The just won't play in Safari on the Mac.

The Owncloud service is running on an Ubuntu 12.04 VM which is running on Windows Azure infrastructure. It is version 5.04.

I'm happy to provide more info to anyone taking on this bug.

Regards,
mike

@unamike: regarding Undefined offset: #923
@icewind1991 this isn't implemented yet, thus no bug, thus an enhancement?

It seems that Filesystem::searchByMime(*) is only searching in YOUR files but not in files that are shared with you.
I created a (inglorious) workaround: https://gist.github.com/Jan1337z/5554266
