Comment 4 for bug 1833400

I have asked around but found no one with access to the bug so far (as I was hoping for some repro steps there). I'll create a PPA for testing, but without sort of clear repro steps it will be hard to process the SRU for an update.

Hence I'm setting this incomplete for more information on how to verify/trigger this come up - which I hope the reporter/affected people might contribute here.

And since all we have from the original description (until we have further info) is "race on shutdown" I think the severity on this is rather low.

If one has that and wants to try the PPA [2] should have what is the assumed fix.

And to help that anyone can continue on this (have all the changes) I opened an MP [3] which allows others to use the branch to continue here.
