Looks good to me,

Reviewed-by: Andreas Färber <afaerber@suse.de>

However one comment regarding your commit message: You missed that I
proposed a different patch before Peter committed his. I wonder whether
mine had the same issue...

BTW there's an old patch from Stefan H. on the list (that I have on my
queue to revisit, help appreciated), to make QTests more verbose even
without V=1.

Regards,
Andreas
