Hello Bastien,

Thank you for pointing this out. It looks like we can replace it with
/usr/share/icons/Tango/scalable/emotes/face-crying.svg, which is
essentially the same icon by same author, but appears to be (slightly?)
better off license-wise - it carries the CC "Public Domain
Certification" [0], although that license appears to be discouraged.

For what it's worth, other folks have neglected to look at the metadata
in the file itself as well.  For example, this page [1] claims public
domain (and the file history claims cc-by-sa-2.5), but downloading the
48x48 file shows that it's the same file that you detected in
xhtmlrenderer, carrying the cc-by-nc-sa license.

For the Java Team, it also appears that xhtmlrenderer has been renamed
to flyingsaucer [2], so we may want to do a sourceful transition once
this bug is addressed.

Cheers,
tony
