Could you take a look for the ParentChannelListener crash, michal?

[Michal Novotny [:michal]]

I think Honza knows the diverting code much better. Can you please have a look?

Comment 3

[Honza Bambas (:mayhemer)]

The crash rate is very low. I know the code somewhat, but not that well - if anyone of the team actually knows it :D I'd wait for the DocumentChannel work to remove diversion altogether rather than invest a minute of time to investigate this bug.

WONTFIXING for now. If we later find out that diversion can't be removed/disabled that easily, we will reopen.
