Ok, I'm getting some errors with the new patch. I did semodule -l on my 
F10 system:

[method@riddler selinux]$ sudo semodule -l
libsemanage.semanage_direct_list: Out of memory!
semodule:  Failed on list!


gdb'ing it I see:
1320                    if ((size = bunzip(fp, &data)) != 0) {
(gdb)
1321                            fclose(fp);
(gdb)
1322                            fp = fmemopen(data, size, "rb");
(gdb)
1323                            if (!fp) {

(gdb) print fp
$1 = (FILE *) 0x0
(gdb) print errno
$2 = 12
(gdb) call perror()
Cannot allocate memory
$4 = 0
(gdb) print size
$5 = 4294967295
(gdb) print module_filenames[i]
$6 = 0x8b34b18 "/etc/selinux/targeted/modules/active/modules/ada.pp"

[method@riddler selinux]$ sudo file 
/etc/selinux/targeted/modules/active/modules/ada.pp
/etc/selinux/targeted/modules/active/modules/ada.pp: data

So this is not a compressed module
