           Summary: Segmentation fault
                    `WebCore::TimerHeapElement::operator=`
           Product: WebKit
           Version: 528+ (Nightly build)
          Platform: PC
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: Normal
          Priority: P2
         Component: New Bugs
        AssignedTo: webkit-unassigned at lists.webkit.org

Created an attachment (id=52515)
 --> (https://bugs.webkit.org/attachment.cgi?id=52515)
gdb traceback of the segfault

I can reproduce a Segmentation Fault that occurs in
`WebCore::TimerHeapElement::operator=` probably because `t` is a null pointer.
The full traceback is attached.

I'm using a rather complex setup: Python + PyWebkitGTK (the Python binding) +
PyJavaScriptCore (a Python JSC binding, [1]) + GObject threads.

I'm sure this has something to do with threads as we're getting *lots* of
threading problems with this setup.

Could please anyone give me a tip what the problem might be so I can do further
research fixing this issue? Thanks! :-)
