If I select the location and start typing something, but don't type too fast, then the new location bar drops down with some suggestions. This is great, except when it tries to find these suggestions it freezes for a second or so which is tremendously annoying.

Perhaps my history is too large and I should clear it, but that's no solution to the problem. Surely this could be done more asynchronously? I've not looked at any of the code but I'm guessing it's reading my ephy-history.xml file (which in my case is 1.7MB) during this blocking period?
