You have three options (well, three that I can think of right now):
1. File a bug and wait for an update to the policy package which does allow this.
2. Change the context of the file you're attempting to attach so that SELinux lets it get attached.
3. Put SElinux in permissive mode, so it will log the fact that it wants to deny this action but it won't actually prevent it from happening.
Each option has drawbacks, some perhaps significant, so the route you take will be highly dependent on your environment.
