Description
Occasionally, when closing a window or tab containing a Flash animation (output to pa via libflashsupport from git.0pointer.de), the browser (Epiphany) will crash, with a fairly useless stacktrace. Very occasionally it will deadlock, with the following trace:
Thread 8 (Thread 0xb4b00b90 (LWP 16863)):
