Overview Description:
There is a reproducible assertion failure in -[WebHTMLView
_handleStyleKeyEquivalent:] using WebKit TOT. This is a regression from Mac OS
X 10.5.7 Safari 4.0.1.

Steps to Reproduce:
1) Unzip, build, and run the attached sample Xcode project "WebViewClose.zip".
2) When the web page stops loading, do command-q to quit.

Actual Results:
Assertion failure.

Expected Results:
No assertion failure.

Build Date & Platform:
git commit 401f9b797d616c4f01bfe3f730b723494afc0ec2 Tue Jun 23 23:06:36 2009
+0000, corresponding to svn r45011.

Additional Information:
The sample Xcode project is actually the same as the one in
<https://bugs.webkit.org/show_bug.cgi?id=26665>. I found this bug while testing
the other bug. However, the bugs do not appear to be otherwise related.

I've attached a crash log. Also, here's the backtrace:
