Comments are for CVS HEAD + FF backend + focus patch applied.

The problem seems to be relative to onblur event where the javascript try to
close the window after catching a focus-out event.

See http://bugzilla.gnome.org/show_bug.cgi?id=172878 for a testcase.

Other ways to crash epiphany in the same context are:

- Ctrl+T to open a new tab, 
- Ctrl-W to close the window

A side effect too: if the sidebar is showed, try to use the combo box to switch
sidebars => crash.

And a random crash to close the comments:

Created attachment 47665 [details] [review]
proposed fix

This patch seems to fix all crash/warning on tab/window close issues. Tested
extensively with the galeon popup testcases; more testing appreciated.
