* SUMMARY Closing a page with a streaming jpeg webcam causes an assertion failure in debug builds of ToT WebKit. * STEPS TO REPRODUCE 1. Open Safari/WebKit. 2. Load URL: http://www.scheveningenlive.nl/beach1.html 3. Close window. * EXPECTED RESULTS Window should close without assertion failure. * ACTUAL RESULTS Assertion failure occurs when closing window. * REGRESSION Not tested with shipping Safari 2.0.4 (419.3) on Mac OS X 10.4.9 (8P135) yet. * NOTES Reproduced with a local debug build of WebKit r21170 with Safari 2.0.4 (419.3) on Mac OS X 10.4.9 (8P135).
This does not occur with shipping Safari, although it's not a debug build.
