There is a new version (1.1.1-maemo2) in extras-devel and extras-testing now, which is rebased onto the proper 1.1.1 version (as tagged on github.com). With this version, AndyTitan's save.cfg doesn't crash for me, so maybe the fixed point error was introduced later. I've also removed some songs from the music package that I believe are not used at all.
Please check if there are problems with this one, and vote for it to enter extras here and here.

Thanks to AndyTitan for the detailed problem description and to Jetrel for the upcoming solution
