Package: netpbm
Version: 2:10.0-8
Severity: normal
The following sequence of commands should result in an identical bitmap,
but does not. It has a small vertical black bar in it.

pngtopnm yellow_red_gradient.png > x.pnm
pngtopnm -alpha yellow_red_gradient.png > y.pnm
pnmtopng -alpha y.pnm x.pnm > z.png

Interestingly, this problem did not occur when I had prelinked my
libraries (debian package "prelink"), but does on both a clean
(never prelinked) and un-prelinked machine.
source image is here, uuencoded:
