Ignore the webkit_tests failure in that build; it's unrelated and already dealt with. I've attempted to reproduce this assertion failure locally without success, so am not sure whether it's a flake or regression. Watching the debug bots for another cycle to see whether WebKit can be rolled. 858965 1 kbr 2013-03-19 18:44:13 -0700 Note: this bot cycled green, so the failure's probably intermittent. However if the assertion failure looks like something that needs to be changed, please make a change. 859028 2 kbr 2013-03-19 20:46:38 -0700 This is happening on more than just this bot: http://build.chromium.org/p/chromium.webkit/builders/WebKit%20Linux%20%28dbg%29/builds/7294 Marking P1 and updating synopsis.
