Seems so... to check this is actually the case, you can call aspcud directly on the cudf you generated, for example

$ aspcud /tmp/solver-error-76189-1.cudf /tmp/sol.cudf "-count(removed),-notuptodate(solution),-count(new)"

In oldish versions of opam, despite the message stating "falling back to the
internal solver", no fall-back was performed, hence the absurd solutions.
This was fixed in trunk by Louis and me recently.
