Fixed it. The problem was indeed related apparmor. My home directory is not in /home and I didn't tell apparmor that. While testing Lucid, my home directory is in /local/home-10.04, and /home -> /local/home-10.4. /etc/passwd and HOME specify /home/reece as my home directory.
The fix was to add /local/home-10.04 to /etc/apparmor.d/tunables/home.d/ubuntu using sudo dpkg-reconfigure apparmor. With that change, the file is viewable with or without the suffix and the tty warnings go away. I stand by the original observation that merely removing the suffix from the filename causes the observed error. This kind of fragility is disconcerting. This makes me wonder whether there should be a loud warning when any home directory is not listed in the apparmor config. (There were no warnings whatsoever in /var/log/ for the problem related to this report.) -- evince unable to open PDF file without suffix https://bugs.launchpad.net/bugs/532956 You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to evince in ubuntu. -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
