Well, my problem here is that Dr Konqui is most useful if you're also shipping debug symbols. For Krita, that's not something I intend to do, so I might actually extend the use of Google Breakpad -- we already do that on Windows.

When I was focusing on Windows I had the same problem with kded4, and I just remove it. That broke Dr Konqui, but then, on Windows that wasn't all that useful anyway. I had to make a couple of really tough decisions and I find I'm in the same position now on OSX: I want to make a package of Krita that conforms to what the regular users expect, so I just cannot have any daemon running. I cannot even have kbuildsycoca4 run after installation, because that's not what Mac users expect.

So right now I'm working on an alternative way of locating and loading plugins. Good exercise, I guess, for the Qt5 port. What I don't get, yet, is the difference between running "bla.app/Contents/MacOS/bla" and "open bla.app"...

I've also noticed a weird bug in kservice, where the type of the variant for custom desktop file keys isn't inferred correctly. That's to say service->property("X-KDE-bla") return nothing unless you specifiy the type like this: service->property("X-KDE-bla", QVariant::StringList)

well, kparts were originally KDE's answer to Microsoft's OLE architecture. They were meant to build compound documents -- so you'd have a text document kpart that would embed a spreadsheet document kpart. That sort of extended into a generic document + gui embeddable object thing. We no longer use it in Calligra, even though it was originally designed for KOffice by Reginald Stadlbauer. There is a big disadvantage to kparts in that it ties together the qwidget-based gui and the document: load the document and you get the gui with it.

Yes, I've got a small and slow macmini. I'm not sure I dare install macports on it, though, because I'm afraid it might interfere with my regular builds.

If the rest of the krita community is fine with that, I might actually do that. I've also created the Krita Foundation to fund Krita development, so we've got a full-time developer on Krita now, and I would like to extend that.
