Bug 146620 – Crash when closing the web inspector

• Component: Web Inspector
• Status: RESOLVED FIXED

[Michael Catanzaro]

We have some rare crash when closing the web inspector:

Core was generated by `/usr/libexec/webkit2gtk-4.0/WebKitWebProcess 42'.
Program terminated with signal SIGSEGV, Segmentation fault.
#0  IPC::Connection::invalidate (this=0x0) at /usr/src/debug/webkitgtk-2.8.3/Source/WebKit2/Platform/IPC/Connection.cpp:345
345	    if (!isValid()) {

There's a full backtrace in the downstream bug; here is thread 1:
