Spacehab being taken to the ISS on the next Shuttle mission isn't an ESA project. And as it's just for storage, I can't see why it would need or have a computer.

You may be thinking of the Automated Transfer Vehicle to be launched by a Ariane 5 later this year.

Was she shoe shopping by any chance?

Both the Automated Transfer Vehicle and Esa's Columbus laboratory due to be added to the ISS in December seem to use the same computers.

Anyway the problem seems to involve the size of the ISS, and the ATV is much smaller. Columbus willl be part of the ISS, but it's computers won't be controlling the Station.

And they now now how to fix the problem even if the cause isn't fully understood.
