Comment 2 for bug 534883

I have the "Segmentation fault (core dumped)" also, however, it is the only error message I get. I have disabled all Addons in Firefox & uninstalled flashplugin-nonfree via apt, the crashes still occur.
I can reproduce the bug by opening several tabs with javascript content and clicking around the links a few times (in my case, reproduced on Wikipedia with monobook.js set up.) Hope this helps to pin down the Bug.
