Bug#486125: Closing a tab with flash kills epiphany-gecko

[Erich Schubert]

Hi,
With the debug packages installed, it doesn't even get as far as closing
a tab. While loading the youtube front page:

Now I can see the youtube front page and the flashblock button, start
the flash and then close the tab (having opened a second tab earlier).

All this is obviously happening in the closed-source flash player.
But if it was triggered by some API breakage it could still be a bug in
xulrunner, the embedding code or something like this.
