  Double-peaked oxygen lines in the nebular spectra of two peculiar Type Ib/c
Supernovae (SN Ib/c) have been interpreted as off-axis views of a GRB-jet or
unipolar blob ejections. Here we present late-time spectra of 8 SN IIb, Ib and
Ic and show that this phenomenon is common and should not be so firmly linked
to extraordinary explosion physics. The line profiles are most likely caused by
ejecta expanding with a torus- or disk-like geometry. Double-peaked oxygen
profiles are not necessarily the indicator of a mis-directed GRB jet.
