Perhaps the change in this commit conflicts with some older code in Ark to work around the old behaviour and which does some additional manual unregistration? Or perhaps some slot in accidentally invoked 2x so the unregistration happens more than once, with the second try than failing? Wild guesses is all I have to offer, sorry. I cannot remember anything questionable about this patch, so no pointers into it, instead my initial reaction would be to look at the consumer side. Yes Ark has a manual unregistration, which I can easily fix. From what I can see, after this change any job registered with KIO::getJobTracker()->registerJob(job); no longer needs to be manually unregistered with KIO::getJobTracker()->unregisterJob(job); This is a minor thing, but should probably be documented somewhere.
