Bug Description
This is possibly related, but not the same, as bug #284147.
After I set the opacity of an imported bitmap (tried png and tif), the colours becomes posterized. This is onscreen, as well as when exported. The more transparent, the more posterized it becomes, but I found that the effect somewhat reverses below 5% opacity.
I made a sample svg from a bitmap with a good range of colours. I'll attach it here, along with a screenshot from inside inkscape as well as the exported image.
I have the latest nightly build (Inkscape 0.47+devel r9389) running on WindowsXP SP2.

Confirmed on Windows XP, Inkscape bzr rev. 9381.
Workaround: insert your image in a group (Ctrl+G) or layer, and then apply the opacity to the group.
