Infinite loop in EliminateMeta with seemingly unrelated option

[jrosain]

Description of the issue

The proof of the attached problem is instantaneous as long as we don't ask Goéland to print it. However, once we want to actually print the proof, Goéland goes into an infinite loop of EliminateMeta and never does print it.
