Agreed, this is bad-Juju.

  "eventfd Bad file descriptor" likely means the 64-bit value contained in the
eventfd has been trampled by another memory problem resulting in Undefined
Behavior. It is likely an Amarok problem as the virtual address space for the
process should keep Amarok walled off from the rest of the processes. That
doesn't mean that PA can't be going haywire and causing the problem if Amarok
and PA are communicated over the descriptor (or other parts of TDE), but my
bet is Amarok is the source of the problem.

  Grab a strace of Amarok when the issue occurs and post that will the
bug-report. That should identify exactly what is failing if it is something
that is hard to reproduce.
