roc, this seems like your kind of thing?  ;)

Comment 2

[Boris Zbarsky [:bzbarsky]]

This worksforme.  Is this still a problem?  If so, in which browser?

Comment 3

[Boris Zbarsky [:bzbarsky]]

Ah, I see it in Firefox.  Have to have the feed viewer, I guess...

So the view in question comes from a nsMenuPopupFrame.  The parent of the view is the view of the ViewportFrame().  And the closest ancestor of the nsMenuPopupFrame that has a view is a CanvasFrame.  view->GetParent()->GetParent() is null in this case.

Note that nsMenuPopupFrame::Init explicitly reparents its view.  Why isn't this hitting us elsewhere?

Note that I can also get this assertion by opening the page setup dialog.

It probably doesn't hit us normally because we rarely create views for XUL content, and popups are usually direct children of the root.  If the closest view to the MenuPopupFrame happens to be the viewport, the assertion doesn't trigger.

Ah, ok.  So probably not worth worrying about this until we remove views?

I hit it with current trunk build of seamonkey when I wanted to close mailer. I just clicked on the File menu and it kicked in. Maybe related to the 'key_openFileMessage' message?

After I 'continued' gdb session the previous thread exited (I closed before the Preferences menu by 'Cancel') and I got opened the File menu of mailer.

I'm hitting this on startup when Firefox needs to bring up the check extensions for updates dialog.
