Hi Daniel,

It takes a while to start, but my application does work.  Is it then
possible to just ignore the alerts for this particular case.  I would
also prefer not to mess with my policies, lack of understanding being
the main reason.

That said, I do have another similar problem with a game in steam:

  SELinux is preventing /home/user/.local/share/Steam/ubuntu12_32/steam
  from using the execheap access on a process.

Raw Audit Messages:

  type=AVC msg=audit(1365646731.47:8579): avc: denied { execheap } for

  subj=unconfined_u:unconfined_r:unconfined_t:s0-s0:c0.c1023 key=(null)

  Hash: steam,unconfined_t,unconfined_t,process,execheap

This time however, the application does not work.  Again, adding the
custom policy fails in exactly the same manner.

This is up to date F18: selinux-policy-3.11.1-87.fc18.noarch.

This does not return anything.

  libsepol.scope_copy_callback: qpidd: Duplicate declaration in module:
  type/attribute qpidd_var_lib_t (No such file or directory).
  libsemanage.semanage_link_sandbox: Link packages failed (No such file
  or directory).
  semodule:  Failed!

The only time I messed with SELinux was when I installed a few custom
file contexts for a change root environment I use for my work.
