Hi Robert,

(sorry for BTS juggling, I found your comment just after I sent the
first email.)

Anyway I agree that the problem needs to be fixed upstream, but I would suggest
that we keep GNU/KFreeBSD build enabled for the moment and if this cannot be
fixed before freeze, we can always disable it. It would be shame to disable this
build right now, because there would be basically no push to make it
work (if there
is more stuff broken than just the tests).

Thus I am downgrading the severity to important, so it doesn't block
transition, and
will take care of GNU/KFreeBSD builds somewhere around June.

Is that ok with you?

Ondrej
