[Bug 276809] SEGFAULTs using libjail

https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=276809

--- Comment #2 from Fabiano Sidler <freebsd-bugs@aliases.systohc.net> ---
Ah, of course I'm an idiot! How can I expect any param to have a value in such
a "list all possible param NAMES" call?
The C program works now as expected, but I still get the SEGFAULT in Python
after the first parameter (zfs.mount_snapshot). What is there still a problem?
