This "newly failing" is the same false alarm as we saw recently. I
think Cuirass gets confused on same package with different versions as
the only one I see on i686-linux building in the past year is v5.

As for the actual error, no idea (I saw the same thing when I noticed
the "new failure"). But I'm cc'ing Efraim as having figured out the
fix for the other package (sorry don't remember which, qt something)
on i686 recently...
