rhythmbox crashed with SIGSEGV in g_str_has_prefix()

[Anthony Harrington]

Reproducible for me - Crashes when finished playing a song and the next song has 2 entries in the library (one of which is invalid and persistently returns after being 'removed' - no actual duplicate .mp3 file exists in the /music folder though.)
So it'll finish playing song a, and if there are 2 bs, it will completely freeze before it hits b, instead of playing the b which correctly links to b.mp3.
Installed rhythmbox-dbg before this bug happened again, so the following data should, hopefully, be useful to someone trying to fix it :)
