Bug 32752 – [GTK] crash when loading new page

• Status: RESOLVED
• Resolution: FIXED
• Component: WebKitGTK

[Benjamin Otte]

Here's an assertion failure I have with WebKit master - so you'll likely need a debug build to trigger it.
Steps to reproduce:
1) http://lwn.net/
2) Click on the: "See the full changelog for lots of details." links in the 2.6.33 story (as long as it's there)

You'll pretty much immediately get an assertion like this:

Program terminated with signal 11, Segmentation fault.
