A simple plumbing problem? How about a design flaw.

There is a reason we have design processes, with independent reviews, and detailed simulations. The idea is to avoid silly, but very costly mistakes. In theory, we learn from past mistakes, nevertheless . . . .

Unfortunately, no amount of independent review, detailed simulations, or design processes provide immunity to the NIH syndrome.

There's a recent postscript to the story in the OP.

Apparently, the two satellites have been moved to better, though not ideal, orbits, which will allow them to function as part of the Galileo navigation system.
