Comment 1 for bug 2044420

Okay, so fuzzy_skip_prefix() in libgtkpod calls g_utf8_collate_key() twice in a loop, once with len=3 and then once with len=2.

I found this by patching fuzzy_skip_prefix() like so:

libgtkpod/misc.c

 458 const gchar *
 459 fuzzy_skip_prefix(const gchar *name) {
 460 const gchar *result = name;
 461 const GList *gl;
 462 gchar *cleanStr;
...
 470 cleanStr = g_utf8_casefold(name, -1);
 471 for (gl = csfk_list; gl; gl = g_list_next(gl)) {
 472 struct csfk *csfk = gl->data;
 473 gchar *tempStr;
 474
 475 g_return_val_if_fail (csfk, 0);
+476 fprintf(stderr, "Song name: %s length: %d\n", cleanStr, csfk->length);
 477 tempStr = g_utf8_collate_key(cleanStr, csfk->length);
...

I get output like this:

...
Song name: fórmula, vol. 2 (deluxe edition) length: 3
Song name: fórmula, vol. 2 (deluxe edition) length: 2

It seems to not like special characters, in this case, the ó.

I also looked on the Arch Linux AUR page, and it seems others have also noticed that special characters are breaking them too.
