Firefox causes Gnome panel to crash (repeatable)

[Aigars Mahinovs]

Binary package hint: firefox-3.0

Opening the following page: http://blog.oup.com/2009/03/science-fiction/
Causes the gnome-panel to crash and restart infinitely until the tab with this page is closed. Firefox remains fully functional during the whole procedure. Window borders also disappeared at one point suggesting that metacity was also restarted. Compiz is not being used.

I tried upgrading all the software and restarting the computer fully. This also happens in a fresh guest session.

The installation is an upgrade from 8.10.

I can confirm on Intrepid.

Can you please test using Firefox-3.5 from our repos using a supported version of Ubuntu.
Firefox-3.0 has reached EOL and will not get anymore updates.

[John Vivirito (gnomefreak)]

Are you still able to reproduce this crash using latest 3.0.17 in repos and with 3.5 from repos

In maverick, no gnome-panel crash but firefox hangs for a wile.

[Aigars Mahinovs (aigarius)]

With Firefox 3.6.10 in Maveric it hangs for some seconds 10-15 and then displays the page ok, no gnome-panel or Metacity crashes. So it is much better now. :)
