Bug 540136

Created attachment 372911 [details]
File: backtrace

It does appear that opening http://docs.fedoraproject.org is more likely to cause this problem than most sites.

Further detail:  Opening the same page from a local sandbox as described in the Documentation Guide (http://docs.fedoraproject.org/documentation-guide/en_US/sn-sandbox-setup.html) will also cause the symptom.

Still more information:

In case it isn't obvious from the data ABRT sent, the crash is an X crash, not just a browser crash. The screen suddenly goes black and a few moments later the greeter appears. It appears to be related to an underlying library since a number of other browsers also experience the symptom:

Arora, Links, Mosaic and Konqueror all work fine, although the page is not fully functional on Links and Mosaic (not a big surprise).

Arora, Kazehakase, Midori and Seamonkey all crash.

I turned up the priority on this since we point to that page in a lot of places.  The page works fine on F10 and F11, but it does fail W3C validation miserably.
