App: GtkLauncher Version: SVN r44405 OS/Platform: Ubuntu 9.04 Linux 2.6.28-11-generic #42-Ubuntu SMP If the properties of a VIDEO tag are read from within the onLoad handler, I get an immediate and repeatable segault. It doesn't require a video even being loaded. Here's the smallest test case that triggers the problem: <!DOCTYPE html> <html> <head> <script> function readVideoProperties() { var v = document.getElementsByTagName("VIDEO")[0]; if (v) { for (p in v) { var e = v[p]; } } } </script> </head> <body onload="readVideoProperties()"> <video/> </body> </html> Note, the problem seems to be reading the property, simply enumerating them is fine. Also, deferring "readVideoProperties" until after load with a setTimeout(0, ..) call prevents the problem.

Can't reproduce the crash with latest upstream using your example.
