 This test check the following situation:
 
 First you navigate to a page (first-page.html).

This is certainly wrong, as it dumps full path, which is machine specific.

Should we roll out <http://trac.webkit.org/r150386>?

[Alex Christensen]

I think r150386 is correct, but it exposes another bug in WK2 or WebKitTestRunner.  We might end up rolling it back, but give me some time to look into this.

[Alex Christensen]

I guess roll it back for now.  I can always submit a complete patch later.

[Alexey Proskuryakov]

This bug should have been closed with the rollout, but I'm now landing that change again, and the test still fails. Will use this bug to track fixing it separately.

How does this not change more tests?

DumpRenderTree changes in this patch are meant to be an inconsequential cleanup. We couldn't have full paths in tests before, because that would fail on all other machines, and we hopefully didn't raise exceptions too much (I only saw that with some other code in my tree).

I am a bit surprised that so few WebKit2 results changed. Perhaps we overused skipping?
