Please file a bug and mark it a blocker to ARMTracker bug. It might be
similar to some of the other ARM ICEs we're getting but I'd sooner
have a dupe than miss a bug. Put the details of the koji tasks in the
BZ and we can either extract the bits needed from the mock chroot or
recreate the build to get the details.

They do, you can also get one via beaker.
