Description Mikhail Naganov 2011-01-20 05:52:12 PST 
From http://code.google.com/p/chromium/issues/detail?id=70228:

Chromium 10.0.642.0 (71590)

What steps will reproduce the problem?
1. Navigate to some page (e.g. google.com)
2. In the same tab, navigate to other page (e.g. yandex.ru)
3. Open DevTools, open CPU profiles page, start profiling.
4. Press the "Back" button in browser.

Expected: tab navigates back to the page from item 1., profiling continues.
Actual: tab renderer crashes.

        * inspector/InspectorProfilerAgent.cpp:
        (WebCore::InspectorProfilerAgent::addProfileFinishedMessageToConsole):
        (WebCore::InspectorProfilerAgent::addStartProfilingMessageToConsole):


I agree, we should investigate the real cause of the crash.

http://trac.webkit.org/changeset/76345 might have broken GTK Linux 64-bit Debug
The following tests are not passing:
