I am seeing this new assertion/crash in my debug build.  I am not sure
if it is a regression caused my hacking around with the directory
viewer or not.  I am guessing not.  Basically this happens sometimes when I 
leave the directory viewer to go to a new page.  The assertion happens here:

(the directory viewer is that xul/tree widget that comes up if you load an ftp 
or file or gopher url)

Waterson's quick guess was:

> NTDLL! 77f9fb83()
> nsView::~nsView() line 158

Line 158 of nsView.cpp is where we call mWindow->Destroy(). (Windows
usually loses a stack frame or two when thunking into the OS.) So,
something we're calling in nsWindow::Destroy() is pumping the event
queue, which causes some more script to be run. :-(


Here is the stack:
