There are a bunch of bug reports about attachment icons, but I didn't see anything current specifically about this. Have you considered opening one at https://bugzilla.mozilla.org
? You might at least get a reply from a developer.
Luckily I did not have to file a bug and expose my self to the hole spam world, seems as they are not that anxious to get bug reports. By trial and error I finally succeeded getting the icons in place.
Prerequisites are gnome-vfs and gnomeui and all there dependencies. I compiled packages available from Slackbuild.org.
Then I had to compile Tunderbird from source adding:
to the mozconfig file. Those options are supposed to be automatically checked for as I understand it. But that didn't work for me so I had to put them there.
Finally, I had to start a gtk theme manager. I use xfce-mcs-manager as that is distributed with Slackware. One must also choose an icon theme that contains all necessary icons. The theme manager needs to run all the time so I put an application link to it in KDE autostart folder. It should, if I understand it correct, pick up specifically application installed icons as well but it seems that theme icons overrides them.
Result can be seen in attached picture with Rodent icon theme.
