With Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.8a5) Gecko/20041023
and a new profile the browser takes over the CPU.
With Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.7.3) Gecko/20041025
Firefox/1.0 and a new profile I get a crash every time.

Robert, this is the only one of your testcases so far which _doesn't_ crash for
me using the 2004-10-25-05 build on Windows XP.

One change in the procedure to reproduce this. Before opening the attachment
disable java. With Java enabled I was able to view it with Mozilla/5.0 (Windows;
U; Windows NT 5.1; en-US; rv:1.8a5) Gecko/20041025. When I disabled java it hung
the same UA and it crashes the latest Firefox branch.

Confirming on Win32 with Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US;
rv:1.8a5) Gecko/20041027 and java disabled. Browser hangs

Status: UNCONFIRMED → NEW
