The svg file that originally had this "problem" when

Firefox. As for the svg file itself, it still isn't viewable on other
svg viewers, even Batik. This probably isn't a problem so much with
Inkscape as it is with other svg "compliant" software. However if
Inkscape is supposed to produce svg which is viewable on other
viewers, then this may be a problem. If I should submit a bug report,
I would be happy to do so, and include the svg file causing the
problem.
Outside of Inkscape I was just viewing a PNG file. The "problem" was
that Inkscape treats the transparency of the background slightly
different when exporting then when rendering to screen (and with good
cause I might add). On-screen a background necessarily has some opaque
color (well, theoretically Inkscape might be able to make the background
transparent, but I doubt anyone would appreciate that), when exporting
this doesn't have to be the case. And apparently IrfanView simply
discards the alpha channel or something, so if anything it's probably a
problem with IrfanView and not Inkscape.
