The latest nightly WebKit build downloaded as WebKit-SVN-r38297.dmg crashes whenever I use the View Source function, whether by menu or shortcut. This happens on multiple sites (including twitter.com and gardnermuseum.org).
Steps to reproduce on my PPC iMac with 10.4.11:
1) Open WebKit.app
2) Browse to a web page (it appears that any will do)
3) View Source through the menu bar or alt-cmd-u.
4) The browser crashes.

Report of the view source crash
I can't reproduce this but it's clear it's trivial to fix. Just need to null-check _private in viewDidMoveToWindow.
