"It's only a safety problem"

I had to say something, I just had too. This just kills me. A low cost Spanish airline flying from Lisbon to Madrid had some of the seats on the plane taped off and would not allow passengers to use them.

The captain told them on the intercom: "We will not be able to use that
part of the plane because we have a safety problem with the door at the
front. Don't worry, it's only a safety problem," the newspaper reported.

Only a safety problem? Well, thank goodness it is nothing serious, like...I dunno, something that might compromise the safety of the passengers.
