Yeah. I forgot mention that detail :)

I first noticed it when I tried starting "/usr/bin/evince"
evince doesn't start and runs into this error.

Happens every time evince is invoked. I tried evince again.

xournal works just fine. xournal doesn't have usr.bin.*file* for
it anyway, so that doesn't matter I would think.

Attached /etc/apparmor.d/usr.bin.evince

thanks,
