address before checkin?

[Henrik Grunell, 2011/11/08 22:06:41]

Yes I will. I'll get back to this shortly.

[tommi (sloooow) - chröme, 2011/11/08 12:27:24]

do we need to delete web_frame here or is ownership elsewhere?

[Henrik Grunell, 2011/11/08 22:06:41]

I think it's only a weak ptr, I'll check this and get back.
