The Chromium Linux dbg canary ( http://build.chromium.org/p/chromium.webkit/waterfall?show=Webkit%20Linux%20(dbg) ) has had major problems with crashing tests in inspector/elements and inspector/styles ever since some time shortly before r100584. The nearest inspector-specific CL before that was http://trac.webkit.org/changeset/100572 for bug 72393, but the problem could also be something else. Specifically, the tests seg fault with no useful back trace. The following tests have failed this way so far: inspector/elements/dom-agent-query-selector.html inspector/elements/edit-dom-actions.html inspector/elements/modify-chardata.html inspector/styles/media-queries.html inspector/styles/metrics-box-sizing.html inspector/styles/styles-add-blank-property.html inspector/styles/styles-add-invalid-property.html inspector/styles/styles-add-new-rule.html inspector/styles/styles-change-node-while-editing.html inspector/styles/styles-commit-editing.html inspector/styles/styles-computed-trace.html inspector/styles/styles-disable-inherited.html inspector/styles/styles-disable-then-delete.html inspector/styles/styles-iframe.html inspector/styles/styles-new-API.html inspector/styles/styles-redirected-css.html inspector/styles/styles-update-from-js.html inspector/styles/styles-url-linkify.html I think I'm going to attempt to roll out r100572 to see if the bot stabilizes.
Looks like r100572 was not the culprit.
r100584 was not the culprit either. I'm giving up on trying to track this down via reverts, I'm just going to suppress these at the moment.
Some of these tests are also timing out - http://build.chromium.org/p/chromium.webkit/builders/Webkit%20Linux%20%28dbg%29/builds/440

The inspector/styles tests have behaved well lately, should I close the bug?
Is there any particular thing we think might have fixed this? I get a little uneasy when bugs magically disappear but no one knows why...
