114413 2013-04-10 23:13:01 -0700 REGRESSION (r147880-r147965): Youtube crash in WebCore::WidgetHierarchyUpdatesSuspensionScope::moveWidgets 2013-04-12 15:41:05 -0700 1 1 1 Unclassified WebKit Plug-ins 528+ (Nightly build) Mac (Intel) OS X 10.8 RESOLVED DUPLICATE 114488 http://www.youtube.com/watch?feature=player_detailpage&v=xRTjHJ93UYg#t=224s InRadar, Regression P1 Critical --- 0 kevin webkit-unassigned abucur ap rniwa oldest_to_newest 873569 0 kevin 2013-04-10 23:13:01 -0700 The crash is on the old youtube channel pages rather than their new one channel layout that some use. It also only occurs when the default video embed on that page starts with an Ad rather than playing the actual content video. I find going to the link above for another video first and clicking the embedded link at the end with the 2 girls Lizzie Bennet Diaries seems to cause an Ad to appear more reliably. It takes you to the channel page "http://www.youtube.com/user/lizziebennet" and proceeds to crash once the Ad starts playing. If the page should load without a video Ad first, then it doesn't crash. Note that if the Ad plays but doesn't crash, don't let the Ad finish playing if you want a better chance of the Ad playing each time for testing. This also occurs with other old style channel pages that start with an Ad as well.

I wonder if the problem was being contributed to by the specific Ad video that was playing and now it's different? Who knows. 874358 2 ap 2013-04-11 22:42:40 -0700 <rdar://problem/13632610> 874359 3 ap 2013-04-11 22:45:03 -0700 I'm wondering if this is the same as 114488. 874974 4 abucur 2013-04-12 14:54:37 -0700 (In reply to comment #3) > I'm wondering if this is the same as 114488. I've rolled back some changes that tried to optimize ContainerNode::removeChildren ( https://bugs.webkit.org/show_bug.cgi?id=114521 ). Things are a lot messier than they initially seemed so we're going to start from square one again (a bit more knowledgeable on the way :) ). 874975 5 abucur 2013-04-12 14:55:43 -0700 (In reply to comment #3) > I'm wondering if this is the same as 114488. Oh, if it's really not reproducing any more, I guess you can close it as a duplicate of https://bugs.webkit.org/show_bug.cgi?id=114521 . It's your call. 874977 6 kevin 2013-04-12 14:59:02 -0700 Yeah, this specific test is no longer reproducing, although I did just have another page crash with the same basic log, but I wasn't able to reproduce that immediately either. 874987 7 abucur 2013-04-12 15:10:45 -0700 (In reply to comment #6) > Yeah, this specific test is no longer reproducing, although I did just have another page crash with the same basic log, but I wasn't able to reproduce that immediately either. Still on YouTube? The log would be useful even without a repro. 875004 8 kevin 2013-04-12 15:40:03 -0700 Actually it's happened twice today. Once on bluray.com, possibly going to Amazon.com via a Buy Now link. Second, on either amazon.com or camelcamelcamel.com since I may have been moving between the 2 via a javascript command at the time. Both crashes look the same.
