Some Applications menu items are missing icons

Each application which lacks an icon needs to have it's .desktop file fixed.

Trying to guess affected packages.
About the missing icon for the "About Xfce" dialog, it seems tango-icon-theme is missing an icon named gnome-info.

For xfce4-session, this is already reported in Bug #58251.

xfce4-session (4.4.1-1ubuntu3) gutsy; urgency=low

  * debian/pixmaps/xfce4-autostart-editor.png.uue, debian/rules: add a menu
    icon (from Jozsef Mak) for the autostart-editor. (LP: #58251,#105493)

some of these are fixed in gutsy
for the others please open a bug on the specific package not default settings or the icon theme

This bug was fixed in the package xfce4-taskmanager - 0.4.0~rc2really0.3.2-0ubuntu1

xfburn now has an icon in trunk, this will be fixed in the future 0.3.0.

It'll be fixed when xfburn 0.3.0 is synced from debian unstable (Bug #240061)

The education icon is also missing. It just shows the red X. I tried all installed icon themes: Human, Tango, GNOME, GNOME-Brave, Rodent. There is always the no icon placeholder shown.

The missing education icon has it's own Bug #392290.

There is also a missing application icon for ePDFviewer in Xfce menu in Ubuntu 9.04 Jaunty Jackelope.

/usr/share/applications/epdfview.desktop

in line 11 it says "Icon=postscript-viewer.png"

I found epdfview.xpm in /usr/share/pixmaps as a replacement and there are some PNG icons in the project trunk: http://trac.emma-soft.com/epdfview/browser/trunk/data

Thank you for taking the time to report this bug and helping to make Ubuntu better. Please submit any future bugs you may find. This missing icon in ePDFviewer has been fixed in ePDFview version 0.1.7-2 included in Xubuntu 9.10. The icon can be found in /usr/share/epdfview/pixmaps/icon_epdfview-48.png.

I am closing it because the bug has been fixed in the latest stable version of Xubuntu - Karmic Koala 9.10. It won't be fixed in previous versions of Ubuntu because the package doesn't fit the requirements for backporting. See https://help.ubuntu.com/community/UbuntuBackports for more information.
