kio crash with latest kdelibs and qt/mac

[Benjamin Reed]

I've been working on updating my snapshots to match the new qt-copy
and latest kde trunk, and it looks like kio is pooched, at least on
mac:

I don't know for certain (yet) that this is the issue, but I notice a
recent change (583210) touches that bit of code in kio, could it be
related?

I don't know enough of what this actually does to be able to tell if
it's related or not.  Any ideas what's going on?
