Description From 2011-03-24 09:55:54 PST
http/tests/inspector/extensions-resources-redirect.html sometimes crashes WebKit2's web process. We know this because the web process crashing then causes the UI process to crash (bug 57029). We don't know what's causing the web process to crash, though, because the UI process crash is masking it.

Ooh, I found a crash log from the web process. See the URL.

Looks like the first time this happened was in r81782, which seems like a related change.

Added the test to the mac-wk2 Skipped file in r81874.

Figured this out.

A serious of events have to happen with both the network layer and the WebProcess -> UIProcess layer to reproduce this.  There's probably no practical way to reproduce the exact conditions necessary in layout-test land, but we obviously already had coverage that caught this.

In fact, the single test Adam deactivated isn't the only one that can cause this - I've seen it locally with other https tests (though less frequently)

Patch is coming soon.
