This is probably partly a philosophy question, since shutting down on
low battery will cut some amount of playtime off. As Dominik Riebeling
mentions in the first comment, a safeguard has been put into the
shutdown code, so that it will abort attempts to save settings after
some number of times, so in some ways, you could argue that this bug is
fixed.
I haven't tested this for a while so I don't know if it was addressed, but I
would argue that the repeated 'trying to save' is horrible and gives the
impression the drive is failing or receiving damage. I doubt any commercial
player would do it. The keyword being 'graceful'.
