At any rate, i can confirm this happens. Now i just need to work out what in the world is actually the cause, because this is a mightily confusing backtrace... Thanks for spotting it :)

Fixed in Frameworks 5.77.

Git commit 6156b2a968664c4e08efbc72e5acea9f1e2ffa22 by Dan Leinir Turthra Jensen.

Honour the job being aborted immediately

Occasionally, a job will be started and then immediately cancelled. This
can cause the job to end up still attempting to run while it is in the
process of being destructed, which in turn leads to accessing bits of
data which are no longer available, and in the end a crash. This fixes
that problem by ensuring we actually honour abort calls internally as
well.

Also adds a little test for listing content, and for switching the sort order.
