Please convert netbeans.png to netbeans.xpm using imagemagick's convert OR upload it to mirrors. The icon specification allows png, xpm or svg PNG is a binary image format, and therefore not allowed in gentoo-x86. SVG and XPM are not binary formats, and therefore OK in gentoo-x86
i put netbeans-6.9.png to distfiles but emerge ignores that file: >>> Unpacking netbeans-6.9.1.tar.bz2 to /var/tmp/portage/dev-util/netbeans-6.9.1/work >>> Unpacking netbeans-6.9.1-l10n.tar.bz2 to /var/tmp/portage/dev-util/netbeans-6.9.1/work >>> Unpacking netbeans-6.9.png to /var/tmp/portage/dev-util/netbeans-6.9.1/work unpack netbeans-6.9.png: file format not recognized. Ignoring. compressing png file just to make portage happy seems weird to me. what is the correct way to handle this file? making xpm file does not seem to me to be ideal solution either, it's pretty ineffective way in this case to store the image.
fixed in 6.9.1. thx to samuli for help.
