+Subject: Fix segmentation fault when collating halfway through
+ multibyte characters
+ When parsing a song name, if it contains multibyte characters, e.g. characters
+ that contain accents, like 'ó', a recent change in glib causes gtkpod to
+ segfault.
+ 
+ This is because fuzzy_skip_prefix() goes 2 characters into the string, and if
+ the second character is a multibyte string, it hits the issue, e.g.:
+ 
+ "fórmula, vol. 2 (deluxe edition)"
+ 
+ Strings are null terminated, so fix by changing g_utf8_collate_key() to use
+ len of -1.
