Excellent!

The problem is probably fixed with this:

diff --git a/sha1_file.c b/sha1_file.c
index a92f023..b7d1a82 100644
--- a/sha1_file.c
+++ b/sha1_file.c
@@ -844,6 +844,8 @@ struct packed_git *parse_pack_index(unsigned char *sha1)
 
 	strcpy(p->pack_name, path);
 	p->pack_size = 0;
+	p->num_bad_objects = 0;
+	p->bad_object_sha1 = NULL;
 	p->next = NULL;
 	p->windows = NULL;
 	p->pack_fd = -1;

Could you confirm it?

However I just don't like the fact that pack structures are allocated 
and initialized in two places, which makes it error prone as 
demonstrated here.  So I'll cook up a better patch that fixes the 
duplication issue.
