Package: epiphany-webkit
Version: 2.22.3-3
Severity: important

Hello Josselin,
after some time of happy "epiphaning", I switched back to iceweasel. Now, I
wanted to try it again... and seems still in a bad shape :(

I tried to open a page with flash content. Epiphany(-webkit) crashes badly.
Here's the full backtrace:

(specifically, the website was <http://badoo.com/signin/>, it works with
Iceweasel, and epiphany-gecko crashes at the homepage, I believe I'll file
another bug :( )

I hope it helps, I'd be very happy to come back to Epiphany :)

Kindly,
David
