As Thiago describes on bug 91046:

"I'm hitting this assertion when running a internal test suite we have here.

Unfortunately I could not create a test yet that maps exactly what triggers this assertion, but what the test suit does is:

- It has a frameset with two frames, one for the test (A) another one for progress (B).
- Loads a test case on the frame A.
- Does some checks to find out when the test is done on the frame A.
- Manipulates the DOM inside the progress frame B.
- Replaces the src from the frame A with a new test case.
- Looks like the crash happens at the moment the src from frame A is replaced.

I could reproduce the crash on Qt too running the same test suite. Any insight?"
