[png-mng-misc] Error message: Image width is zero in IHDR

[Simon A. E. <gr...@gm...>]

Hello list,

Is there anything wrong with this PNG?
http://granjow.net/uploads/temp/s1.png

I get error messages:
> libpng warning: Image width is zero in IHDR
> libpng warning: Image height is zero in IHDR
> libpng error: Invalid IHDR data
when loading it with TV-L1[1]. No matter whether I export the PNG with GIMP 
or create it wit imagemagick.

thanks
Simon
