###!!! ASSERTION: This is unsafe! Fix the caller!: 'Error', file /work/mozilla/builds/2.0.0/mozilla/content/events/src/nsEventDispatcher.cpp, line 514 Steps to reproduce: -> Use the latest Personas Demo on a Mac Debug Build - see Bug 598144 -> Change a Persona -->> Assertion ###!!! ASSERTION: This is unsafe! Fix the caller!: 'Error'

The stack for the assertion would be useful.

(In reply to comment #1) > The stack for the assertion would be useful. yeah attached, sorry had problems to run fix_mac_stack before.

sWebShellWindow::HandleEvent(nsGUIEvent*) (nsWebShellWindow.cpp:360, in XUL) nsCocoaWindow::DispatchEvent(nsGUIEvent*, nsEventStatus&) (in XUL) (nsCocoaWindow.mm:1420) sCocoaWindow::ReportSizeEvent() (nsCocoaWindow.mm:1482, in XUL) --[ToolbarWindow setDrawsContentsIntoWindowFrame:] (in XUL) (nsCocoaWindow.mm:2355) sCocoaWindow::SetDrawsInTitlebar(int) (nsCocoaWindow.mm:1690, in XUL) sXULElement::SetDrawsInTitlebar(int) (nsXULElement.cpp:2424, in XUL) nsXULElement::UnsetAttr(int, nsIAtom*, int) (in XUL) (nsXULElement.cpp:1441) nsGenericElement::RemoveAttribute(nsAString_internal const&) (in XUL) (nsGenericElement.cpp:2407) Somewhere in here it seems like badness is beginning. Can we maybe call nsXULElement::SetDrawsInTitlebar asynchronously or off of a scriptrunner? Or rather, make nsXULElement::SetDrawsInTitlebar call into the widget code off of a scriptrunner/asynchronously?

Just want to verify: is this blocking progress on bug 598144? I'd really like to be able to get the add-on updated since it is one of our most popular add-ons. Is there anything I can do to help get movement on this bug if so?

cc'ing Neil. Neil, do you know if we can call nsXULElement::SetDrawsInTitlebar asynchronously? Or from a scriptrunner?

I do not know, but it doesn't look like it would be a problem.

Let's do it!
