Looks like the frames and views get out of sync. Specifically the ScrollPortView gets 2 children added to it. But ScrollPortViews can only have 1 child. Not sure why this happens. A tool that can grahically show frames and views relationships would be nice.

Hey, Eric. You holding out on today's checkin? Something left in your tree? Your checkin comment said you got this bug too (but it's still crashing in this evening's win2k build, from after your checkins today). [Actually, I was going to reopen, but then, duh, wasn't closed yet.]

cc bryner, hyatt
moving to moz0.9.1. Is this causing a real-world problem? In what application? Have you put a workaround in place?
Target Milestone: mozilla0.9 → mozilla0.9.1
Would have been nice for our specialized application, but since I couldn't find a workaround, we just changed the UI instead...

trees are deprecated, for multi-column please try outliner. ->future

Attached file command line output (deleted) —
I have a similar problem. I go to www.yahoo.com. Then I click on finance. That page displays. When I scroll down using either the mouse or the keypad mozilla Milestone 0.9.1 crashes. I have previously attached a file with some command line output.
tree is no more
