Bug#278750: librsvg2-bin: rsvg program doesn't handle -h 0 or -w 0 well

[Jason Dorje Short]

Package: librsvg2-bin
Version: 2.8.1-1
Severity: minor


If I call "rsvg -w 30 -h 0 foo.svg foo.png", rsvg gives a cryptic 
warning and a random bogus output PNG.  It should give a useful error 
message and (I think) no output PNG.

(process:26064): librsvg-WARNING **: rsvg_start_svg: width and height 
not specified in the SVG, nor supplied by the size callback

The same is true if a negative value is given.
