[PyQt] QWebHistory load/save

[David Bronke]

Sorry, I spoke to soon. Using out.__lshift__(view.page().history()) yeilds a
zero-length file. Attached is another somewhat minimal test case; it loads
google, wikipedia, and CNN one after the other, and when CNN is loaded, it
saves the web view's history to a file and checks the file's length. On my
machine, this invariably comes out to 0 bytes.

Qt version: 4.6.1
PyQt4 version: 4.7.1-snapshot-20100120 (I couldn't get anything but the
snapshot to install correctly)
Python version: 2.6.4
OS: Arch Linux

Should I update to the latest snapshot and see if that fixes anything?
