I skipped it to paint the bots green: r138710. Please unskip it with the proper fix.

I don't know how to build the Qt port on any platform, so unfortunately can't help debug what's going on. You could try adding more calls to gc() at the end of the test, to try to force collection of the objects associated with the worker and the iframe's DOM.

Qt uses JSC, correct? Since it does, I'd expect it to behave similarly to the Mac port with respect to garbage collection of JavaScript wrappers. The new test seems to be passing on all the Mac bots.
