Torbutton app-blocker wrapper creates high load on FF5 startup

I'm using TB 1.4.0 with FF5 (5.0+build1+nobinonly-0ubuntu0.11.04.2 from Ubuntu). Recently I noticed that the system load was very high when I start Firefox. So I have an empty session with an empty start page. When I start FF it takes lots of seconds until the FF window shows up. During this time the cpu load is ~100%.

I did a git bisect today and found out that commit 81624d96f2427bf2f1be7893d0bd08c1f9b38f61 causes the problem. Within the file src/components/external-app-blocker.js this was added: || method == "getTypeFromURI". If I remove this and install TB, it starts without any huge load or large startup time.

Can we get any log lines or confirmation here other than suggesting we remove some random line of the source code? Perhaps a log message indicating it is being exercised somehow?

This doesn't seem to happen on any platform with TBB 3.0.
