Installed from:    SuSE RPMs

When using random album play in juk, it should differentiate albums with the same name but different artists; currently it will play both albums "together", playing track 1 from the first, then track 1 from the second, then track 2 of the first, etc, etc.

I have a patch for this that I'll attach to the bug for consideration.

Proposed patch for bug 120363

This just adds the "artist" tag to the list of tags used in the search when
defining the next album to play; a quick test showed this to work w.r.t. this
bug (I haven't checked if that method is used from other parts of Juk).

Correct mimetype.

SVN commit 499931 by mpyne:

Fix bug 120363 (JuK should use Artist information in album random play).

Previously, only the Album name mattered, which meant that common names like "Greatest Hits"
would play different artists.

Thanks to the reporter for providing a reference patch.
