            Bug ID: 141713
           Summary: Web Inspector: CRASH under
                    WebInspectorProxy::closeTimerFired
    Classification: Unclassified
           Product: WebKit
           Version: 528+ (Nightly build)
          Hardware: All
                OS: All
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: Web Inspector
          Assignee: webkit-unassigned at lists.webkit.org
          Reporter: burg at cs.washington.edu
                CC: graouts at webkit.org, joepeck at webkit.org,

                    webkit-bug-importer at group.apple.com

How this seems to happen for me:

1. Run debug build
2. Open Inspector
3. Inspector process crashes (for me, at ASSERTION FAILED: m_cachedThreadGlobalTimerHeap)
(?)
4. UIProcess tries to close the WKWebView after a timeout
(?)
5. Crash
