Bug 125461 – [GTK] [Stable] Crash in tbpl.mozilla.org

• Component: WebKitGTK
• Status: RESOLVED FIXED

[Alberto Garcia]

This seems to be in JSC.

It crashes in 2.2.3 but works fine in 2.3.2.

A couple of backtraces. This is GtkLauncher with webkitgtk 2.2.2:

Patch

I bisected this, looks like backporting r155480 (which depends on
r155466) solves the problem.

I tested this patch with WebKitGTK+ 2.2.4

Patch

Somehow the previous patch was compressed, hopefully this one is fine.

Merged in stable branch as r164281 and r164282. Thanks
