I know this issue exists, I've been trying to debug it for a long
time. The most useful thing for me now would be _detailed_
_instructions_ to _reproduce_ it. Please don't comment saying that you
are also affected unless you have found a way to reliably or at least
semi-reliably trigger it.

Everyone,
I know this issue exists, I've been trying to debug it for a long
time. The most useful thing for me now would be _detailed_
_instructions_ to _reproduce_ it. Please don't comment saying that you
are also affected unless you have found a way to reliably or at least
semi-reliably trigger it.
