another tricky crash on quit bug --not sure if this is mailnews, theme, or outliner [toolkit] issue. pls do reassign as needed. using 2001.04.11.08 commercial verif bits. seems to only occur on Mac. i've gotten four identical stack traces --each time i was using the modern-mojo [test] theme, as well as viewing mailnews. i've tried to narrow down a simplified set of steps, but i cannot seem to get a reliable recipe --but it might involve switching btwn the regular and alternate 3pane layouts... 1. in mailnews window, open Preferences and change the layout to the alternate 3pane style. 2. quit the app --> crash. if you don't crash with those steps, try going back and forth btwn the two layout styles, and maybe even having a browser window open when you quit [esp since you may encounter bug 75114]. trace info for talkback incident ID 28998741: 0x00220004 nsCOMPtr_base::assign_from_helper() [nsCOMPtr.cpp, line 63] nsOutlinerBodyFrame::Destroy() [nsOutlinerBodyFrame.cpp, line 305] nsFrameList::DestroyFrames() [nsFrameList.cpp, line 41] nsContainerFrame::Destroy() [nsContainerFrame.cpp, line 95] nsBoxFrame::Destroy() [nsBoxFrame.cpp, line 1006] nsFrameList::DestroyFrames() [nsFrameList.cpp, line 41] nsContainerFrame::Destroy() [nsContainerFrame.cpp, line 95] nsBoxFrame::Destroy() [nsBoxFrame.cpp, line 1006] nsFrameList::DestroyFrames() [nsFrameList.cpp, line 41] nsContainerFrame::Destroy() [nsContainerFrame.cpp, line 95] nsBoxFrame::Destroy() [nsBoxFrame.cpp, line 1006] nsFrameList::DestroyFrames() [nsFrameList.cpp, line 41] nsContainerFrame::Destroy() [nsContainerFrame.cpp, line 95] nsBoxFrame::Destroy() [nsBoxFrame.cpp, line 1006] nsFrameList::DestroyFrames() [nsFrameList.cpp, line 41] nsContainerFrame::Destroy() [nsContainerFrame.cpp, line 95]

I've seen this too, when closing the mail 3-pane.

this is a dup of a bug that hyatt owns. several dups on this one today.
