Yes indeed there is a bug in the b-tree code, other people reported this issue 
as well. Could you run the attached python script on the disk image that causes 
the crash and send me the output file (xattr.bin) ? The script extracts the 
extended attributes file and does not reveals anything about the files 
contents. Thanks.
