Apparmor stops evince from running the helper program /usr/bin/dvipdfm, which evince uses when printing dvi files.
Here's the apparmor audit line from dmesg:

type=1503 audit(1255613594.858:24): operation="exec" pid=2889 parent=2876 profile="/usr/bin/evince" requested_mask="::x" denied_mask="::x" fsuid=1000 ouid=0 name="/usr/bin/dvipdfm"

The result is that it is no longer possible to print dvi files. Presumably the apparmor profile for evince should be taught that running /usr/bin/dvipdfm is ok.
