Hello. I produced another backtrace. Backtraces appear to be random to me. If its helpful I can produce some more backtrace at a later time.
I think that "A parser-blocking, cross site" message on console is unrelated. The message comes very often. Also way before it crashes. I think I may better switch Akregator to use an external web browser that I hardened before in the future.
