Comment 3 for bug 1552796

That places the blame squarely on Midori. Oh well.

I know of a few leaks (and have a private branch where I've been working to fix some of them) but it might be nice to know exactly which are triggered simply by reloading. If it isn't too much trouble, it'd be great if you could run under valgrind and get some info on where leaks come from. I can do that while trying to fix this, but I don't know when I'll have a chance, and it would make my life easier to go into fixing directly rather than having to profile it myself and then fix.
