I do not know much about these snapshot calls, but let me ask you.
You wrote that it's crashing, but here you are saying it gets paused
only, so which statement is correct?

If you have the problem with "downstream" version (here you are saying
it's from Ubuntu), please check it with current master as well.  That
can help us (or someone from Ubuntu) find the reason for it to fail.
It's also possible there are some patches applied only in your
downstream version on top of 1.0.0 and we're mostly dealing with
upstream versions here.
