Whoops, I forgot to delete that member from an earlier attempt at handling the delegate's geometry.

Same as above.

That's because of a design issue in the OCS API and Attica. OCS supports 10 total homepages. The counter starts at 2 because the first homepage property is labeled as "homepage" in the OCS API and exposed by Attica simply through Person::homepage(), but the others are "homepage2..10" in the OCS API and exposed only through Person::extendedAttribute() in Attica.
I'm going to add a brief comment about this in the code to avoid confusion.

The geometry of the row changes, if I don't call layoutChanged() the rows start overlapping at some points and the whole view looks borked.

> The present review request contains the implementation of a Social About Dialog feature for KDE apps, and is a rewrite of Amarok's Social About Dialog (See http://teom.wordpress.com/2009/08/23/social-desktop-integration-in-kaboutdialog/ ). For those who don't have time to read through that link, the Social About Dialog is an evolution of our old KAboutDialog which adds optional Open Collaboration Services features to complete the contributors' data.
> The only changes that concern the API are in kaboutdata.{h,cpp}, and I've tried to keep it binary compatible to the best of my abilities by following the instructions on our Techbase, I hope I did it right.
> The only new dependency is the Attica library, except if we are building with KDE_PLATFORM_FEATURE_BINARY_COMPATIBLE_FEATURE_REDUCTION, in that case all social features are #ifdef'ed out and the dialog behaves very much like the old KAboutDialog.
> The dialog itself uses model/view/delegate, not very different from KNewStuff3, and most of the action happens in the model (jobs to get data from Attica/OCS) and in the delegate.
> As we're getting dangerously close to the string freeze, I've decided to put this up for review even though there are still a couple TODOs in the code. These are:
>  * The icons are placeholders, we are going to need some real icons for links and social networks. We already have some of those for Amarok's about dialog but this needs to be cleanly solved in a way that would not make us liable for IP infringement in any way. IANAL here so a discussion as to how to proceed is welcome.
>  * In the optional translators tab there's a short but not very short text about the translation team. I've added it as a label but it tends to take a bit more room than I'd like, so I'm requesting for comments on what to do with it. Also, I don't know how translators' names are added. If translators can't add their OCS usernames anyway then I'll easily revert to the old about view for them and the problem of the tall translation team text is automatically solved.
>  * Since kdeui does not depend on KIO, I couldn't use KIO::get and had to use QNAM instead. For the same reason I had to use QDesktopServices instead of KRun::runUrl() to launch URLs. As it is now, stuff works, but to make it nicer the plan could be to add an Attica::PixmapFromUrlJob (which I've been told would satisfy other unrelated needs too) to Attica to remove the single instance where QNAM is used instead of KIO.
