The performance test Speedometer/Full.html is crashing since r174226 <http://trac.webkit.org/r174226>
I have double checked this: locally reverting r174226 fixes the issue.
I'm attaching a backtrace from the GTK port that I obtained running the following command on r174267:
$ Tools/Scripts/run-perf-tests --platform gtk --release -2 Speedometer/Full.html
The issue is not GTK specific, it happens on all platforms:

Ok, this is a stupid mistake on my part. Fixing.
