Looks like a bug in libdee, hopefully there's enough information here for mhr3 to sort it out... ;-)

[Michal Hruby (mhr3)]

Doesn't seem to contain any public information, so marking as public.

Looks weird that we're trying to flush the revision queue during processing of invalidation, but it would be useful to see the console log that leads to the crash, as I think there'd be some extra criticals/warnings.

Status changed to 'Confirmed' because the bug affects multiple users.
