animated gif is all black

[besthiker]

I produce an animated gif using
mogrify -format png -page A4 -trim -density 100 -rotate "270<" fluffy.ps
and then
convert -delay 15 *.png -loop 0 myanimation.gif

on my mac (Version: ImageMagick 6.8.9-8 Q16 x86_64 2014-10-07) the convert command works. On linux (ImageMagick 6.8.9-8 Q16 x86_64 2014-09-29 ), the animated gif is black. Each individual image looks fine on the mac and on linux. You can see them here.

I narrowed down the issue to convert as the same pngs worked on my mac and not linux. I included the mogrify command just in case. I need the command to work on linux.
It did in our previous convert version.

Looking at the output from "identify -verbose", the one that works has

• Page geometry: 1041x842+98+0

for every frame, while the one that fails has

• Page geometry: 1041x842+98+65305

So it's displaying OK, but the interesting part is off screen. You can use the +repage option to get rid of the offsets.
