Package: joe
Version: 3.1-0.2
Severity: important
Since the latest "sudo" security update (DSA-946) that joe can't be run from
sudo. It segfaults.
>From the ltrace and strace output it seems that joe segfaults because
sudo doesn't pass along the HOME environment variable anymore.
If ran with "sudo -H joe ...", it doesn't segfault (-H forces sudo to set
the target user's home as the HOME variable).
