No, it's r597. The QHash functionality was added to QVariant only in Qt
4.5. For the time being I'd suggest to use r596 which should build
correctly for you (you can use `svn up -r 596` to backdate your working
copy) until these experimental issues are resolved.

@Jonathan: I haven't had time to look at your approach for window
position saving, yet, but I experimented some time ago with registering
my own struct for QVariant via Q_DECLARE_METATYPE. This worked well for
me at the time, and it's supposed to be supported since (before?) Qt
4.3. Plus it has the advantage of presenting us with a simple,
expandable data structure directly. Back then, I also added a "line"
property to reopen files at the line last selected. Unfortunately, I
never got around to flattening out all issues (in particular race
conditions when re-opening a document, when one part of the code tries
to restore the window layout and another part tries to save the current
settings to the recent docs list). But if you're interested I could send
you what I have some time.

Cheers,
Stefan
