	dfaureUnsubmitted Done Why did you remove this? It's just a more user-friendly version of the QVERIFY on the next line, so it can't possibly have failed while the next line passes... dfaure: Why did you remove this? It's just a more user-friendly version of the QVERIFY on the next line…
	tcanabravaAuthorUnsubmitted Done the text was really not friendly, it was a big blob of diff content pasted on screen. Considering that the next line will also fail I replaced this by saving the diff file on disk, this way we can actually look at the file that failed and take the time to understand the error. tcanabrava: the text was really not friendly, it was a big blob of diff content pasted on screen.
	dfaureUnsubmitted Done OK, this needs a hint for the person debugging regressions then. Something like QVERIFY2(content == contentRef, "Failure, see foo.diff"); dfaure: OK, this needs a hint for the person debugging regressions then. Something like QVERIFY2…
