As a result, menu roles aren't set, or rather, they're left to Qt's default setting, which means that without a patch it (Qt) will use text-based guessmatics ("heuristics") to determine which action should go under OS X's Application menu items About and Preferences. Esp. that Preferences menu item is a delicate one, given how many Configure actions there tend to be. I'm adding the required setMenuRole() calls to put the correct Configure action under the Preferences menu item, where this isn't already the case.

Flow will start identifying itself as Flow in the menu bar, but before I added the setMenuRole() call (see previous point) there was a Configure Karbon menu; the About will also be for Karbon ... and in order to open vector graphics documents for editing it's calligraflow I have to start. The Karbon application does the opposite. Any idea what might cause this?

The backtrace shows that this is due to nested event handling that is the result of deleting a QObject-derived object inside an event loop that has events queued for it (or deleting it from a thread that didn't create the object). To be exact, the crash occurs in QAction::isEnabled which gets called because of some kind of menubar update event, presumably after the corresponding menu has been deleted.
> Does this ring a bell? The likely fix is to use `foo->deleteLater()` instead of `delete foo` (see the documentation for deleteLater()), but what object(s) would need to be treated that way? Presuming that this is not somehow related to the karbon/flow "masquerading" ...

The DrKonqi application that launches appears not to take my settings into account: it opens with default dimensions instead of the last used dimensions, and shows icons in its buttons (which it shouldn't). Worse, I'm running a patched kde-runtime version that lets DrKonqi call lldb ... and this functionality is absent from the DrKonqi that gets called. Does this mean that a local copy of the relevant code is being used?
