As the summary says, fast/profiler/dead-time.html crashes gtk bot, see: http://build.webkit.org/builders/GTK%20Linux%20Release/builds/7223/steps/layout-test/logs/stdio
I suspect this could be related to bug 33490 or bug 32643 or several other bugs relating to unexplained crashers and the inspector like bug 33552 or bug 33377 or bug 30835.
This seems to be passing now on GTK+, so I'll close this bug.
