Well, she couldn't seem to type in the data, so that's all we can think. It's odd as wifey plus sprogs travel every 6 weeks or so, sometimes more often and frequently through the (appalling) MAN T2. The passport in question has less than 6 months before it expires, but again this shouldn't have caused a problem as the flight was within the EU.

I have had a few grumbles in the past few months at MAN about my old style passport also, although never that it has caused such a delay.
