After upgrading Sailfish OS to Fiskarsinjoki 220.127.116.11 the Media application (music player) will not start. I discovered this around one week ago and have tried various tricks to solve the issue.
My music files are stored on a 32 GB SD card, in top-level directory Musikk with one subfolder per album and, as far as I can recall, all in OGG format. International characters (such as the Norwegian characters æ, ø and å) are used in both directory names and file names. This has not been an issue before, the SD card contents have not changed since before the update to 18.104.22.168
I tried using the utility in settings to clear the media database, but that did not help. I can access and play the files from file manager (Cargo Dock). The application Muuzik! also works (nearly) fine - but it has an issue with the international characters.
I have now updated Sailfish OS to 22.214.171.124 - but there is no change in behaviour with regards to this problem.
I thought I would try one more solution before reporting the bug. I shut down the phone and removed the SD card. After restarting the phone the Media application could be started. I reinserted the SD card, and the Media application immediately updated its display with the songs, albums and artists available on the SD card. However, after closing the Media application it will not start again.
Edit 2016-10-25: Updated title to reflect the latest finding; this is a language-specific bug that applies to Norwegian and Danish, but not to other West-European languages or Russian (I have not tried the more exotic (to mee) languages). Added link to Fiskarsinjoki release notes. Added media-player tag
