New crash information added by DrKonqi

Sometimes, when Akregator starts, it isn't able to reload tab contents (which is strange, as I'm connected and Konqueror is able to reload its content)
When I try to manually reload one of these tabs, I get a crash.

kontact (4.4.5) on KDE Platform 4.5.1 (KDE 4.5.1) using Qt 4.7.0

- What I was doing when the application crashed:

I was reading this interview* on one Akregator's tab. When I clicked on "Screenshot Kontact Mobile", I didn't get a button to go back to the interview so I right-clicked and chose refresh (or does it say "reload"?), and Kontack crashed.

I wonder how come this bug status is still set to unconfirmed, despite all the confirmations that followed.

Git commit 9fc90718955ac7665607fb32006a10584a553009 by Montel Laurent.
Committed on 03/10/2012 at 19:02.
Pushed by mlaurent into branch 'KDE/4.9'.

Fix Bug 218310 - Kontact crashed because Webtab could not be reloaded

[QMetaObject::changeGuard, QPointer<QAction>::operator=, QMenuPrivate::activateAction]

FIXED-IN: 4.9.3

We reload => widget is deleted => menu after exec will crash
