This problem is temporarily solved by c16168/16169. Note however, that the cause for it is still not fully understood. In particular, it seems that Amegic's decomposition of massive gauge boson propagators for degenerate momentum configurations causes problems if the spinor gauge is different from k0_n=1 (default). If you decide to investigate this issue further, please reopen the ticket.
