oo look - I found it :-D
clientStuff.py - starting at line 516 it says:
for hdrfn in hdrlist:
hdr =3D readHeader(hdrfn)
(e, n, v, r, a) =3D getENVRA(hdr)
if rpmDBInfo.exists(n, a):
(e1, v1, r1) =3D rpmDBInfo.evr(n, a)
rc =3D compareEVR((e1, v1, r1), (e, v, r))
# if the rpmdb has an equal or better rpm then delete
# the header
if (rc >=3D 0):
log(4, 'Deleting Header %s' % hdrfn)
os.unlink(hdrfn)
if not HeaderInfo.exists(n, a):
# if its not in the HeaderInfo nevral anymore just kill it
log(4, 'Deleting Header %s' % hdrfn)
os.unlink(hdrfn)
well if the hdr isn't needed b/c there is a good enough one in the rpmdb
AND it's no longer in the header.info anywhere well, then it's being
deleted twice.
apply this patch see if you see it anymore. If it works then It'll go
in.
thanks
