This video on ZDNet crashes Webkit immediately and Safari 3.1.1 after about 30 sec to 1 min. (G4 eMac + OSX 10.4.11)
Please provide a crash log: <http://webkit.org/quality/crashlogs.html>.
I cannot reproduce the reported crash bug in WebKit r39572 so I close this report as WORKSFORME. Michael, feel free to reopen this report if you still experience crashes in the latest WebKit, but please attach crash log, as Mark said in comment 1. See <http://webkit.org/quality/bugwriting.html> for more information about the sorts of information to include.
