Description Luca Weiss 2019-08-06 20:21:45 UTC 
Originally raised by me in https://bugs.kde.org/show_bug.cgi?id=407918#c12 but that was a different issue.

SUMMARY
When ~/Music is a symlink to somewhere else, no music is found by elisa because of that:

org.kde.elisa.baloo: rootPaths: ("/home/luca/Music")
org.kde.elisa.baloo: LocalBalooFileListing::triggerRefreshOfContent "/mnt/hdd/Music/Monstercat/Monstercat 020 - Altitude/16. Muzzy - Lost Metropolis.mp3" does not match root paths

So basically the symlink has to be resolved. After changing the Elisa config to not point to /home/luca/Music but to /mnt/hdd/Music, my music finally appeared.

(for debugging baloo stuff in elisa, the command 'env QT_LOGGING_RULES="org.kde.elisa.baloo.debug=true" elisa' is quite useful. keeping this here for easy finding by me)

STEPS TO REPRODUCE
1. Point Elisa to a folder which is a symlink
2. Observe that no music is being found by elisa

Comment 2 Luca Weiss 2019-08-22 18:53:46 UTC 
So the fix is good when ~/Music is a symlink but this breaks when the root path is set to a subfolder of the symlink, so e.g. /home/luca/Music/ProleteR (where, when the symlink is resolved, it's /mnt/hdd/Music/ProleteR).
