reassign 711584 libjavascriptcoregtk-3.0-0 thanks Turns out, as pointed out by Michel Dänzer, that this is a bug in webkit, see: https://bugs.freedesktop.org/show_bug.cgi?id=48441 https://bugs.webkit.org/show_bug.cgi?id=89358 I'm building a package with the patch backported to 1.8, let's see how it goes. Cheers, Emilio
