working apparmor profile for debian sid

Hi,

I've installed the latest package from debian sid:

$ apt-cache policy ricochet-im 
ricochet-im:
  Installed: 1.1.4-2+b1
  Candidate: 1.1.4-2+b1
  Version table:
 *** 1.1.4-2+b1 500
        500 http://ftp.de.debian.org/debian sid/main amd64 Packages
        100 /var/lib/dpkg/status

AppArmor chokes on this because permissions for ~/.local ~/.cache ~/.config prevents ricochet from correctly setting up the config, directories and local user environment when launched for the first time. The effect is that ricochet starts, appears to be working at first sight but actually is unable to maintain state (a unique ricochet id across application restarts).

Here is a working /etc/apparmor.d/usr.bin.ricochet config:

  owner @{HOME}/.cache/Ricochet/ rw,
  owner @{HOME}/.cache/Ricochet/** rwkl,

  owner @{HOME}/.config/gtk-3.0/* r,
}

Note that this will still result in errors from fontconfig (which should be solved with including abstractions/fonts and I've not been able to track this down yet - though it doesn't seem to do any harm)

I'm aware that this should be reported to the debian maintainers however I've noticed some issues with apparmor mentioned here so I thought I'll also report this here.

thanks for this piece awesome software!!
