Comment (by Peter_Dyballa@…):

 Since versions 6.6.x at least ImageMagick has these problems. There are
 two: when it uses librsvg-2 it computes the wrong size of the SVG image,
 first without librsvg-2:

 {{{

 0:00.000
 }}}

 Now adding librsvg-2:

 }}}

 The same can be observed (at least) on G4/PPC 7447A hardware. The second
 problem seems to be related (at least) toG4/PPC 7447A hardware:
 {{{
 - with librsvg-2 display displays SVG in false colours
 - without librsvg-2 SVG images are displayed black&white
 }}}

 I'm trying to see whether my bug reports lead to improvements, so I am
 building up-to-date ImageMagick installations.
