Description of problem:
The PNGs don't contain tRNS chunk, so pixels with color index 0 (corresponding
to transparent in the GIFs) are opaque (light-blue).
Version-Release number of selected component (if applicable):
Steps to Reproduce:
There's nothing to reproduce, look at the PNG chunks.
Or, one can view e.g. /var/www/icons/blank.png (should be completely
transparent) with any PNG capable tool (gqview, mozilla) to see it's light-blue
This is deliberate AFAIK since MSIE does not support PNG transparency.
I don't understand how a blue background which breaks the icons in all
browsers can help MSIE users (except as a inferiority complex cure,
because now they don't work for anyone instead of just them).
