Thanks for your expertise. I see that the thread for second bug
report has continued for over 6 years. I didn't even have Sun
hardware when it started.
As it turns out, I have been using iceweasel 3.0.7 from unstable for
a day now and this is the only page I have encountered so far that
crashes the browser. I'll continue to use iceweasel and simply use
something else for eBay for the time being.
me@ultra5:~$ ulimit -c unlimited
me@ultra5:~$ iceweasel --verbose https://signin.ebay.ca/ws/eBayISAPI.dll?SignIn

I have never done any debugging so I'll have to read up on it.
Given that I am still using kernel 2.6.21 for X11 on this machine
and seeing the issues some others here are having just installing
the operating system on their hardware, this browser problem does
not seem that significant.
