GNOME Panels crash on viewing HTML page in Firefox

[e2l]

(this is my first bug report; don't know whether I should file this under GNOME, Firefox or Pango package)

As described in the German Ubuntuusers forum (http://forum.ubuntuusers.de/topic/firefox-springt-in-vollbild-bei-aufruf-einer-/), the GNOME Panels "crash" (they disappear) when you view a special HTML page in Firefox.

If you load this page in a tab, the GNOME Panels disappear. When you close the tab, the Panels re-load.

The page is the following: http://blog.oup.com/2009/03/science-fiction/
(if they might change it, I copied the source code: http://paste.ubuntuusers.de/394705/)

It seems that a strange character in the HTML title is causing this. If you copy the title into Google and search, the same problem appears: http://www.google.de/search?hl=de&q=+++Nine+Words+You+Might+Think+Came+from+Science+but+Which+Are+Really+from+Science+Fiction%E2%80%A8%E2%80%A8++%3A+OUPblog&btnG=Google-Suche&meta=&aq=f&oq=

(the first character after "Fiction" seems to be it; although it doesn't seem to be enough to copy it, I had atleast to copy "Really from Science Fiction" + the following invisible characters, to cause the crash at Googles SERP)

There seems to be a similar (old/unfixed) bug report: http://bugzilla.gnome.org/show_bug.cgi?id=318863

I got the same behaviour when i got to this page (via planet.ubuntu.com):
http://mrooney.blogspot.com/2009/04/email-deliverability-rfc-2142.html

Gnome-Panel tries to reload an infinitive amount of times, but fails to do so until i close the tab:

Thank you for taking the time to report this bug and helping to make Ubuntu better. Does this occur with the release version of Jaunty with updates?

As far as I can tell, the problem is solved. The pages referenced to by e2l and me do not crash anymore. Supposedly a fix is released.
