Bug Description

I get the following error in the console when trying to play a mp3 file using Rhythmbox:

(21:23:27) [0x832a60] [rb_shell_player_error] rb-shell-player.c:2443: playback error while playing: Problem occurred without error being set. This is a bug in Rhythmbox or GStreamer.

I don't get the same error while trying to play the same file using 'Video's. I installed the required codec using the 'Video's application as it told me to install a codec.

I'm not sure why but running

cd ~/Music
find . -exec touch '{}' \;

As suggested by does appear to fix the issue.

Same issue here on Fedora22. The "touch trick" did not work for me.

 can't play MP3 files via Rhythmbox when the file source is a ZFS pool :( -- it works fine from a non-ZFS storage device. (Fedora 22, 4.4.13-200.fc22.x86_64, zfs =, rhythmbox = 3.2.1-1.fc22) -- anyone know of this issue?

 I'm wondering if there's some sort of "setting" which needs to applied to the pool. It's definitely a "rhythmbox integration" issue of some sort ... as playing through standard gnome-player works regardless of storage source.

(had this tab open in a really old browser session ... doing some clean up ...)

retested on Fedora 26, it works! (bug no longer present)

$ sudo zfs list | grep music
zstorage/music 7.40G 84.9G 7.40G /zstorage/music

rhythmbox opens, music library on that pool, music plays

4.14.14-200.fc26.x86_64, zfs-0.7.5-1.fc26.x86_64, rhythmbox-3.4.1-3.fc26.x86_64
