Bug 52808 – Web Inspector: [Chromium] REGRESSION: Using the "Back" button while profiling causes renderer crash

• Component: Web Inspector (Deprecated)
• Status: RESOLVED FIXED

[Mikhail Naganov]

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.

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