When switching <iframe mozbrowser> in bug 1240896, there are some intermittent crashes at MessageLoop::DeletePendingTasks in non-e10s debug runs. These error seem pretty harmless from what I can tell, but they will need some investigation to make sure of this. I believe this is related to <iframe mozbrowser remote> starting up a child process and then killing it once the frame is removed on non-e10s runs. With e10s runs, the child process remains alive longer since it's used for other activities as well. So, I think this is mostly an accidental thing we've run into due to the timing of how the process shuts down on non-e10s runs.
